  • Practical Reuse of Activated Carbon in the Exhaust Facility of Semiconductor Production Factory with Supercritical Carbon Dioxide Regeneration

    Yasuyuki Ito, Ikuo Ushiki, Yoshiyuki Sato, Hiroshi Inomata

    Publishing type:Research paper (scientific journal)   Publisher:EDP Sciences  

    An possible reason why the activated carbon used in the exhaust facility of real semiconductor production factory could not be regenerated by scCO<sub>2</sub> regeneration was estimated to be attributable to its high boiling point adsorbates which showed a peak in TGA (Thermogravimetric analysis) curve at 400-900°C. This study was conducted to experimentally verify the above insight by using TGA analysis and scCO<sub>2</sub> regeneration for the real samples with different loads from the factory. The experimental results showed that high boiling point ratio defined by TGA analysis was less than 4.0% in case of the heating treatment temperature of 200 °C in the exhasut facility of real semiconductor production factory. This result suggested regeneration rate of the activated carbon was higher than 80%. Our scCO<sub>2</sub> regeneration process can achieve high efficiency as a practical application.

    For better understanding the phase behaviors of heavy oil converting processes, vapor-liquid equilibria (VLE) for hydrocarbon (toluene or n-decane or decalin) + atmospheric residue (AR) light fraction systems were measured at 300, 340, 380 ℃ and 5 MPa by a flow type apparatus. The fractions used were most light fraction (Fr. 1) and fairly heavy fraction (Fr. 4) of which T_b ranges were about 124〜382℃ and 465〜490℃. The experimental data obtained in this work were correlated by Peng-Robinson equation of state to gather with van der Waals one fluid model. The correlations indicated that the Fr. 1, wide T_b range fractions, would be devided into five sub-fractions to make T_b range reasonable.

    Vapor-liquid equilibria (VLE) for toluene + heavy oil, n-decane + heavy oil and cis/trans-decalin + heavy oil systems were measured by a flow type apparatus at temperatures ranging from 573 to 643 K. The experimental data obtained in this work were correlated by Peng-Robinson equation of state with van der Waals one fluid model. The critical parameters and acentric factors were estimated using the Marrero-Gani and Constsantinou-Gani group contribution methods. The correlation results could represented the VLE data well by applying Gao method to the fitting of the binary interaction parameters (k_<ij>).

    A Flow-type apparatus was developed to measure vapor-liquid phase equilibrium of water-heavy oil mixtures at high temperature and pressure conditions. Equilibrium phase samples were collected and analyzed by GPC for oil contents and by Karl-Fischer titration for water. Phase observations through view window suggested that the mixtures showed vapor-liquid two phases, then vapor-liquid-liquid three phases and liquid-liquid two phases with increasing pressure. Measured vapor-liquid phase equilibrium composition indicated that the water content in vapor phase decreases and the water contents in liquid phase increases with increasing pressure.

    Evaluation of CO<SUB>2</SUB> storage capacity in water saturated reservoir rocks is very complex because various trapping mechanisms that act at different rates are involved and, at times, all mechanisms may be operating simultaneously. Thus, in terms of the water saturated reservoir rocks, a reliable estimate of CO<SUB>2</SUB> storage capacity requires a thorough understanding of the mechanisms of CO<SUB>2</SUB> trapping in this system.<BR>The objective of this study is to provide a fundamental knowledge about interactions among CO<SUB>2</SUB>, water and rock, and contributes to development of standards for CO<SUB>2</SUB> storage capacity estimation in the water saturated reservoir rocks. In this experiment, CO<SUB>2</SUB> sorption was measured for rock samples (quartzose arenite, greywacke, shale, granite and serpentine) , and mineral samples (quartz and albite) in a CO<SUB>2</SUB> rich dense phase at 50ºC and 100ºC, and pressures up to 20MPa, the condition of which is expected to occur mostly during CO<SUB>2</SUB> injection into pores of the water saturated reservoir rocks. The result obtained from the experiment exhibited a significant sorption capacity of CO<SUB>2</SUB> on all of the samples. At 50ºC and 100ºC, quartzose arenite indicated largest sorption capacity among the other samples in higher pressures (>10 MPa) . Furthermore, comparison with model prediction based on the pore filling model, which assumed that pores of the rocks and minerals will be filled with CO<SUB>2</SUB>, suggested the importance of the sorption mechanism in the CO<SUB>2</SUB> geological storage in addition to the pore-filling mechanism.<BR>The present results indicate that the sorption process may have significant and meaningful effect on the assessment of CO<SUB>2</SUB> storage capacity in geological media.

    Sorption isotherms, which describe CO<SUB>2</SUB> storage capacity of rocks, are important for estimating CO<SUB>2</SUB> sequestration potential of geological reservoirs. This study examined CO<SUB>2</SUB> sorption capacity of Kimachi sandstone and Iidate granite in the CO<SUB>2</SUB> rich dense phase, the condition of which is expected to occur mostly in the course of CO<SUB>2</SUB> injection into geological reservoirs because of the displacement of formation water by CO<SUB>2</SUB> pressurization in geological reservoirs as storing CO<SUB>2</SUB> into aquifers, at geological temperature and pressure. CO<SUB>2</SUB> sorption measurements were conducted using both volumetric and gravimetric methods at temperatures of 33∼200°C and pressures up to 20MPa. It was found that Kimachi sandstone and Iidate granite were capable of sorbing CO<SUB>2</SUB> into their internal structures. At 50°C, the amount of CO<SUB>2</SUB> sorption reached the maximum value of 1.4 mmol/g (= 31.4 scc/g) for Kimachi sandstone and 0.7 mmol/g (=15.7 scc/g) for Iidate granite, respectively. Comparison among model predictions (monolayer adsorption, solubility and pore-filling) suggests that the sorption of CO<SUB>2</SUB> onto rock minerals may contribute to a significant portion of the CO<SUB>2</SUB> storage capacity in the course of CO<SUB>2</SUB> injection. <BR>This investigation points out the significance of CO<SUB>2</SUB> sorption onto rock minerals for the possible mechanism in CO<SUB>2</SUB> geological storage.

    Language:English  

    The phase equilibrium of the H&lt;sub&gt;2&lt;/sub&gt; + cyclopentane binary clathrate hydrate is important because cyclopentane (CP) has been shown to reduce the equilibrium storage pressures similar to that of tetrahydrofuran (THF). In this work, we apply correlations for the H&lt;sub&gt;2&lt;/sub&gt; + CP binary clathrate hydrate system based on the Gibbs free energy and the Kihara potential. The correlation is also applied to the H2 + THF binary clathrate hydrate system and compared with literature results. It was found that the models could correlate both H&lt;sub&gt;2&lt;/sub&gt; + CP and H&lt;sub&gt;2&lt;/sub&gt; + THF sufficiently. From the calculated hydrogen occupancies and the Langmuir constants of CP and THF, the relationship between hydrate dissociation enthalpy and hydrogen occupancy was studied. The hydrate dissociation enthalpy varied according to phase equilibrium conditions at low pressure. The Langmuir constant of CP was lower than that of THF which implies that the formation of CP clathrate hydrate is more difficult to form than THF clathrate hydrate. As hydrogen occupancies became higher, the hydrate dissociation enthalpies of H&lt;sub&gt;2&lt;/sub&gt; + hydrocarbon binary clathrate hydrate approached a constant value.

    Vapor-liquid equilibria (VLE) and liquid-liquid equilibria (LLE) for water-decane and water-squalane (C_<30>H_<62>) binary mixtures were correlated by Peng-Robinson Equation of State (PR EoS) at temperatures ranging from 573 to 637 K and pressures ranging from 1.3 to 31.2 MPa. The boiling point and critical constants of squalane were estimated from the specific gravity and molecular weight by using Nji method whose applicability to heavy hydrocarbon had been approved by comparing the prediction accuracy for the literature critical constants of paraffins, naphthenes and aromatics. Introduction of two temperature dependent binary parameters into mixing rules was revealed to provide good correlations and it was also suggested that the temperature dependence of volume binary parameter was omissible to reduce the number of parameters in calculations.

    Anthropogenic effects on the climate can be mitigated through various artificial measures. Amongst others CO_2 sequestration on geological reservoirs including deep saline aquifers, depleted oil/gas reservoirs, and coal seams is expected to provide a powerful means for drastically reducing emissions of CO_2 to the atmospheric. It may be an important step to understand the capacity of the host reservoir rock for CO_2 storage in order to assess the potential of CO_2 geological sequestration. In this study, CO_2 sorption capacity of rocks (granite, sandstone and natural quartz) under air dry condition was evaluated experimentally at temperatures of 50 and 100℃, and pressures up to 20MPa using a magnetic suspension balance (MSB), which allows us to measure the rock weight under the presence of supercritical CO_2. The CO_2 sorption isotherms of the rocks obtained showed that the CO_2 sorption capacity increased with the increasing pressure and decreased with the increasing temperature. Especially, the CO_2 sorption isotherms of the natural quartz were nearly the same as that of the granite. The present experimental results obtained from the weight measurements suggest that the sorption of CO_2 onto silica minerals may be the important mechanism for the CO_2 storage in reservoir rocks.

    Microalgae can be regarded as potential biomass resources because of their rapid growth and simple constituents. For utilization the microalgae as biomass, it must be clarified what are controlling the growth rate and the composition of constituent component in microalgae cultivations. In addition, effective utilization may require the cascade processes consisting of separation of valuable components from microalgae and conversion of residuals to useful components. This study was conducted by using Chlorocuccum littorale as a microalga. The experiments were conducted to firstly study the effects of culture conditions (temperature, gas composition and irradiance) on both the cell growth rate and carotenoid productivity and to secondly apply the supercritical CO_2(sc-CO_2) extraction to caroteniods separation from freeze-dried microalgae. The results revealed that the cell growth rate was enhanced by elimination of O_2 from aeration gas and decrease of brightness of light, and that the sc-CO_2 extraction exhibited lower carotenoid selectivity and higher extraction yield with adding ethanol as an entrainer.

    Poly (ethylene terephthalate) (PET) foam was produced with a batch-wise method using carbon dioxide and nitrogen as physical blowing agents. Saturation pressure and temperature dependence of the foam structure was investigated. Solubility of the gases in PET and crystallinity of the PET induced by gas sorption were also investigated. PET foamed with CO<sub>2</sub> at 323K and pressures higher than 10MPa had very fine cell structure (cell number density of 10<sup>12</sup>cm<sup>-3</sup> and average cell diameter of 0.4μm). On the other hand, pressure dependence of the cell structure foamed with N<sub>2</sub> was similar to results of amorphous polystyrene foam, whose cell structure became fine with increasing pressure. Volumetric expansivity of the PET+CO<sub>2</sub> system rapidly decreased with increasing pressure, whereas that of the PET+N<sub>2</sub> system gradually increased with increasing pressure. Cell structure foamed with CO<sub>2</sub> became coarse with increasing saturation temperature. In the case of N<sub>2</sub>, saturation temperature dependence of cell structure was not observed at higher than 400K regardless of the solubility increase. These results suggested that cell structure and volumetric expansivity related not only to crystallinity but also to crystalline structure.

    An apparatus for measuring the PVT properties of polymers using a metal bellows was developed for pressures up to 200MPa and temperatures from 313K to 473K. The relationship between the volume of the sample cell and the displacement of the bellows was determined measuring the PVT properties of water for temperatures up to 473K and pressures up to 200MPa with an accuracy of ±0.1%. The PVT data for mercury measured with the apparatus showed good agreement with literature values. The PVT relationship for polystyrene was measured in the same ranges of temperature and pressure. The estimated uncertainty in data was less than ±0.0053cm<sup>3</sup>/g. The PVT data in the rubbery state were correlated with three equations of state. The Simha-Somcynsky equation of state showed the best agreement with experimental values.

    Botryococus braunii, BOT-22 can be a producer of hydrocarbon which is secreted naturally from the cell body. It can be useful that some extraction methods can recover with no damage to the living cell, leading to a hydrocarbon production with continuous cultivation. We assessed the "milking" method for a non-destructive hydrocarbon extraction according to literature. In the milking experiments, a heptane extraction solvent was used and rapidly contacted to culture media. Then, a vortex mixer was used for mixing the contents. The extracts recovered by heptane was analysed by GC-FID. The results showed that the mixing and extraction time are very important for the milking and the extracted hydrocarbon was from 3 to 7 wt%-dry cells at each extraction time. After separating the algal cells from the extraction solvent, a fresh culture medium was added to the culture medium and after the 5 days, the cell concentration was recovered. Thus, a method for continuous hydrocarbon production from Botryococus braunii was fairly assessed.

    Cobalt supported on mesoporous silica were prepared via supercritical CO_2 and methanol entrainer at temperatures ranging from 40 to 80 °C, pressures ranging from 16 to 20 MPa and a reaction time of 5 h. The highest yield of cobalt loaded in the silica was 9.9 wt% and the value was obtained by the repeated processing at 60°C, 20 MPa and methanol concentration of 10 mol%. TEM analyses showed highly dispersed cobalt particles in the mesopores. Fischer-Tropsch reactions (230°C, 1.1 MPa) using the obtained catalysts after calcinations was revealed the CO conversion of 46.7 %, which was about 1.5 times higher than the conventional incipient wetness method.

    CO_2 sorption experiments for Berea sandstone, Kimachi sandstone, shale, serpentine, granite, quartz, and albite were conducted using the gravimetric method under air dry conditions at 50℃ and 100℃, and pressures up to 20 MPa. In higher pressures (>10 MPa), Berea sandstone has shown a significantly higher sorption capacity compared to the other samples at both 50℃ and 100℃. It is also shown that the major component minerals for the rocks tested in this study (quartz and albite) have a CO_2 sorption behavior. Comparison of model prediction which assumes that the CO_2 storage capacity of the rock mass is equal to the amount of CO_2 used to fill the pore volume in the rock, suggests that the CO_2 sorption is an additional CO_2 storage mechanism in storing CO_2 process. The present results indicate that the CO_2 sorption characteristics may provide a significant and meaningful effect on the assessment of CO_2 storage potential in geological storage.

    Solubilities and diffusion coefficients of high-pressure gases in polymers are important in the production of polymers. This article reviews techniques to measure these properties at high pressures. The pressure decay method measures the change in the amount of a solute gas in its vapor phase with the dissolution of the gas in a polymer. This technique requires a precise measurement of pressure. The electric balance method measures the weight of a polymer sample with an electric balance installed in a high-pressure chamber. Temperatures and pressures are limited in this method. The magnetic suspension balance method is a newly developed one. An electric balance outside the high-pressure chamber and a polymer sample are connected magnetically. This method can measure the gas solubility most accurately and can be used with a wide range of temperatures and pressures. Diffusion coefficients of gases in polymers are evaluated by applying an appropriate diffusion equation to measured uptake.

    We developed a hydrothermal cutter which can prepare any paste from Perilla leaves and stems by tuning the operation condition such as water/sample ratio and temperature. The obtained paste contains the particles whose size is under 1.0 micro meter. This paste was used for prepare the concentrated solution which could be continuously separated/fractionated into flavor compounds and resin ones by using supercritical counter current extraction tower in which the system was rectified by vapor-liquid phase separation induced by tuning temperature/pressure/feed ratio conditions. The simulation method was also proposed based on the Vapor-liquid equilibrium ratio(K-value) information.

    高圧CO2を希釈溶剤の代替として用いるCO2塗装技術はVOC削減、乾燥エネルギーの低減が可能であるなど、魅力的な技術である。しかしながら真溶剤の選定によっては問題が生じることが知られており、本研究では塗膜の品質にかかわる塗料の粘度に関して、塗料+CO2混合時の粘度を評価し、塗料に使用される真溶剤の最適化を図ることを目的とする。
    本研究では、ポリマーを溶解する有機溶媒は粘度低減効果が大きいものを選定する必要があり、CO2溶解時の粘度の予測法の提案を目指す。このための鍵として、ポリマー溶液の粘度とSP値の関係を明らかにすることで、粘度挙動を把握することができると考える。本研究では以前に溶解性の研究で使用したpoly(bisphenol A-co-Epichlorohydrin) (PBE)をポリマー試料としCyclohexanone、 N-N-dimethylformamide (DMF)、Dimethyl sulfoxide (DMSO)、Nmethyl-2-pyrrolidone (NMP)を溶媒として、大気圧下での粘度を測定した。さらに一部の混合系についてCO2を添加した際の粘度への影響を測定した。この結果、溶媒の多い(ポリマーの稀薄な)混合系には、自由体積理論に基づく粘度推算法の適用性が低いことがわかってきた。また、溶液粘度と純溶媒の粘度比(ポリマーによる粘度上昇率)はポリマーと溶媒のSP値の差に影響を受けていることが明確になってきた。これはポリマーと溶媒のSP値が近いほど、線形に粘度上昇率が高くなっており、SP値から粘度上昇率が推定できることを意味している。すなわちポリマーと溶媒の親和性が大きいほどポリマーが溶液中で空間的に広がり、粘度が相対的に高くなっている可能性があることがわかった。

    Mixed-solvents, properties and catalytic systems related to efficient processing of biomass with ionic liquids and supercritical carbon dioxide (scCO2) were studied. Basic physical properties (solute activity coefficients at infinite dilution, high pressure densities and CO2 solubilities) were measured and theoretical relationships were developed. Characterization of solvent polarity was studied by measuring Kamlet-Taft parameters of mixed-solvent systems where it was found that solvent phase polarity could be advantageously controlled with solvent-phase composition. Appropriate catalysts, ionic liquids, supercritical and catalytic systems were identified, whereas hydrogenation of biomass-related substrates with bifunctional catalysts was studied. A hydrogen-free, ionic liquid-scCO2-formic acid-bifunctional Ni/NiO catalyst reaction system that produces gamma-valerolactone in high yields (97%) with unprecedented efficiency (3 h) was developed as one example.

    Microalgae is gaining attention as a potential new feedstock for biorefineries. Current methods used to obtain oil from microalgae require drying steps, which consumes much energy and the usage of organic solvents. In this work, we developed a wet extraction method using surfactant active ionic liquids (IL) and supercritical CO2 (scCO2). IL are applied to solubilize microalgae oil in water, and to improve contact efficiency with scCO2. Wet oil extraction was conducted from microalgae (Botryococcus braunii) in the cultivation solution with IL and scCO2 which confirmed that the extraction yield increased greatly by adding ILs in the culture compared to pure scCO2 extraction.

    CO2 painting method was developed for reduction of volatile organic compounds emission. However, due to the addition of CO2, a polymer which is a coating film component in the paint may precipitate, and countermeasures are urgently required.
    To solve this problem, the applicant showed that it is possible to prevent precipitation of polymer by changing the true solvent, while keeping the film forming component (polymer) as it is, and suggesting a solvent selection guide using Hildebrand solubility parameter. In order to further improve accuracy and ease of prediction the precipitation pressure, the applicant proposed a solvent selection guide using Hansen solubility parameter (HSP).

    For developing synthesis methods hydrocarbon by hydrogenolysis of cellulose in ionic liquid-supercritical CO2 biphasic systems, high pressure densities and CO2 solubilities were measured. Theoretical methods were developed for estimating both CO2 and H2 solubilities in ionic liquids. An apparatus for designed, built and tested for measuring H2 gas solubility in the presence of CO2 with ionic liquids. A theoretical metric, denoted as the enhancement ratio (ER) was proposed and used to assess the increase or decrease that H2 solubility that can be obtained with supercritical CO2. Ionic liquids that dissolve biomass were theoretically assessed with the metric and equations of state. The enhancement of H2 solubility by CO2 was observed from experimental measurements. The properties measured and the theoretical methods developed allow estimation of reaction conditions for the synthesis of many types of chemicals derived from cellulose.

    Prediction of adsorption equilibria of volatile organic compounds (VOCs, toluene, n-decane, n-hexane, acetone and methanol) on various adsorbents (activated carbon, zeolite, mesoporous silica and mesoporous carbon) under supercritical carbon dioxide conditions was investigated with a new methodology by using the non-ideal adsorbed solution theory (NIAST) coupled with the Dubinin & Astakhov (DA) equation. The proposed DA - NIAST model could provide accurate predictions of VOCs adsorption equilibria on the various adsorbents in comparison with the conventional methodology by using the ideal adsorbed solution theory (IAST).

    Supercritical fluid extraction-distillation system for separation of high-value products from natural resources was developed. In this system, orange peel powers were extracted by supercritical CO2 with an addition of ethanol and the extract was transferred to thermally controlled distillation tower in which in which extract constituents could be separated into upstream and downstream according to vapor-liquid phase equilibrium for CO2-ethanol systems at specified temperature and pressure. For evaluation of the developed apparatus, two substances (7-hydroxy flavone and anthracene) possessing the similar chemical structures were selected as test samples. The results of distillation showed that the anthracene was highly concentrated in the distillate from the top of the distillation column without accompanying 7-hydroxy flavone at pressure of 12 MPa and temperatures of the tower controlled to be between 353 K at the top and 363 K at the bottom. Nobilethin is one of the highly active natural compounds was also concentrated in the distillate from the top by adding a slight amount of water entrainers. It was demonstrated that the developed system was well-worked towards the highly-selected separation of polymethoxyflavone from Citrus peels.

    Separation of biomass dissolved into ionic liquids using CO2 as antisolvent was studied. In the dissolution step, cellulose decomposed in some of the ionic liquids. However, ionic liquid, which was composed of acetate anion, showed negligible decomposition after 50 h at 40 ℃, regardless of whether it was pressurized or not. Gelation of cellulose-ionic liquid solution occurred at pressures 7 MPa, 25℃. Above 50℃, gelation did not occur. Viscosity of the solution decreased with increasing CO_2 pressure. Since gelation of cellulose with ionic liquid and CO2 occurs, separation of lignin from cellulose in actual biomass may be possible.

    This is the final report for the project, Development of a high-temperature, high-pressure, continuous microplant for super high speed reactions. In this project, our goal was to develop a conceptual microplant reactor system that could be used to bypass many of the current technological limitations of using high-temperature, high-pressure water such as safety, plugging with solids, and corrosion. To do this, we used the concept of a batch microreactor, that would be used in a continuous manner like that of a printing press. In this way, the use of hydrostatic pressing would allow safe application of pressure, and ideally, chemical heating by mixing two or more substances together, would allow achievement of supercritical conditions and thus high-speed reactions. By performing high-temperature, high-pressure reactions in this manner, it is possible to solve known technological problems. First, reaction of cellulose mixtures were studied. Then, a gel was evaluated for transporting the cellulose mixtures including its reactivity.. Next, chemical heating was studied with thermal methods including thermographic imaging. Finally, reactivity of high concentration mixtures was studied.
    In this project, we could make progress toward the topic and made the following accomplishments: (i) patent for describing the apparatus (Japanese, English), (ii) study of cellulose hydrolysis reaction at high-pressures (> 600 MPa) in a batch microreactor, (iii) evaluation of a gel suitable for transporting the cellulose into the microreactor and its reaction characteristics, (iv) experiments and evaluation of a method for chemically heating the mixture in a microreactor to reaction condition, and (v) various presentations on aspects of the project. Aspects of the work that will require future study include: use of catalysts, choice of substrate for transporting materials, separation methods for product materials, and throughput and process control. In conclusion, the system designed is practical and can be used to process materials at high-temperatures and high-pressures with great safety and with highly-reliable operation.

    Conventional processes for micronization of polymers have several disadvantages. Recently, PGSS (Particles from Gas Saturated Solutions) process that uses supercritical fluids (SCF) attracts much attention as a solution of the disadvantages. SCF is dissolved in a molten polymer and the high-pressure mixture is rapidly depressurized through a nozzle. By cooling effect in course of expansion the polymer is solidified leading to particle formation by precipitation. Since PGSS process do not require the dissolution of polymers in SCF phase, this process can be applied to wide range of polymers and the application is investigated to pharmaceuticals, catalysts, paints, biopolymers, and foods. However, researches of this process are scare for polymers and mechanism of micronization and effect of process parameters are not known enough.
    The objective of the present work is to investigate the effect of initial temperature, pressure, SCF concentration and nozzle structure on the average particle size, particle size distribution and shape of resulting particles. Experiments were carried out for poly (ethylene glycol) (PEG) and polyester with supercritical carbon dioxide. As the results, fine particles of PEG with average molecular weight of 4000 could be obtained quickly at temperatures higher than 313 K, pressures higher than 10 MPa and CO_2 concentrations higher than 70 wt%. The average diameter decreased with decreasing temperature, increasing pressure, and increasing CO_2 concentration. By simulating the path of temperature and pressure during the decompression based on the energy balance, it was found that the period when the polymer is in liquid state decreased with decreasing temperature, decreasing pressure and increasing CO_2 concentration, and therefore the average diameter decreased and the shape changed to non-sphere. However, the effect of pressure in this simulation was opposite to the experimental results and the reason for this was considered to the change in the velocity of the mixture in the nozzle.

    キャピラリー式粘度計を用いてポリスチレン+CO_2系の粘度を170,180,200℃、圧力0.1〜40MPa、CO_2濃度0〜5wt%の範囲で測定した。また、得られた粘度を用いてEOS-free volume modelならびにChow-WLF modelによる推算性の検討を行った。これらのモデルはCO_2濃度零の粘度の圧力依存性を十分には表現することができなかったが、CO_2混合下では30%程度の偏差を生じるものの定性的には良好な推算が可能であった。この推算において、ポリマーの占有体積の見積にファンデアワールス体積の代わりにサンチェーラコンベ状態式の特性体積を用いることにより推算精度の向上が可能であった。また、零せん断速度での粘度が重要であることがわかったので、落球法による粘度測定装置を作製した。

    Crystallization rate of polylactide induced by supercritical carbon dioxide was measured with a FT/IR spectrometer equipped with a high-pressure diamond ATR cell. Absorbance change at 1266 cm^<-1> was related with crystallinity obtained from X-ray diffraction (XRD). It is hard to extract the crystallization rate from experimental observation, because solute diffusion rate in polymer is usually small and the crystallization follows sorption of the solute. The ATR method used in this work, however, will measure only the crystallization rate, because polymer sample can be thinner (about 10 μm) in this method and sorption equilibrium accomplished less than 9 s. The crystallization rate of four kinds of sample thickness (10, 50, 100, and 250 μm) was measured to make sure this. While the rate of the absorbance change decreased with increasing the thickness of the 100 and 250 μm sample, sample thickness dependence on the rate did not be observed in the sample thickness of 10 and 50 μm. Therefore, we used the samples of thickness from 10 to 20 μm. The crystallization did not be observed with XRD at CO_2 treatment pressure of 1 and 2 MPa, whereas the crystallization was observed with FT/IR. This observation means possibility of small crystallite existence, which can not be detected with XRD. DSC measurement of CO_2 treated sample was carried out to make sure the existence. The crystallization temperature decreased with increasing the increasing the treatment pressure. This result means the existence of small crystallite. The crystallization mechanism was made clear through the absorbance change measurements. The mechanism consists of two steps, at first small crystallite rapidly forms and then growth of the crystallite begins.

    Microcellular plastics (MP) is a newly innovated foam plastic material that includes numerous cells of very small sizes in it. This material has many advantages over conventional foam plastics, such as superior thermal, mechanical and electrical properties, as well as environmentally accepted production process and product because of using benign gases such as carbon dioxide and nitrogen.
    In this study the effects of saturation pressure, saturation temperature, decompression rate, time to start heating, heating temperature and heating time on the cell structure (average cell diameter, number density of cells and expansion ratio) were studied in batch-wise production of foam polystyrene using carbon dioxide and nitrogen as blowing agents. The experiments were carried out mainly at high temperatures above the glass transition temperature of the polymer where industrial production processes are operated. This work proposed a "quick heating" method, in which dissolution, decompression and heating processes are performed continuously in a high-pressure chamber. This new method could utilize the dissolved gas for foaming effectively and control the cell structure widely. As a result, it was found that increasing pressure (gas solubility) increases number density of cells and decreases average cell diameter, that the effect of increasing temperature is different for different gases, that increasing decompression rate increases the nucleation rate of cells, that short interval between decompression and heating processes results in the larger cell diameter, and that heating at high temperatures first increases cell diameter but decreases it later. Furthermore, the relationship between process conditions and cell structure was expressed qualitatively by extending classical nucleation theory and cell growth theory and by considering various properties of the polymer - gas mixture accurately.

    Solubility and diffusivity of gas in polymer are important properties for development and process control of polymer production plant. The gas solubility and diffusivity under high pressures and temperatures are needed for production of polymeric foams, In this work, the solubility and the diffusivity of following systems were investigated.
    Solubility and diffusivity:
    Gas : C0ィイD22ィエD2
    Polymer : polystyrene, polypropylene, high-density polyethylene, poly(butylene succinate), poly(butylene succinate-co-adipate), poly(vinyl acetate)
    Gas: NィイD22ィエD2
    Polymer : polystyrene, polypropylene, high-density polyethylene
    Solubility :
    Gas : HCFC-142b, HFC-134a, HFC-152a
    Polymer : polystyrene
    These systems were expected as new polymeric foam materials, since CFCs (chlorofluorocarbons) as conventional physical blowing agents were banned. Experimental results of the solubility were correlated by the Sanchez-Lacombe equation of state in conjunction with a temperature dependent interaction parameter. The interaction parameter determined from fitting the solubility was inversely proportional to absolute temperature. The diffusivities could be correlated with the free volume theory by Stern et al.

    溶融状態における溶解度については、本研究で用いたポリマーでは温度・圧力と溶質が同じであればどのポリマーにおいても全て同じ溶解度を示した。この事からコモノマー含量が20mol%程度の範囲では溶質の溶解度には影響を及ぼさないことが明らかになった。
    溶融状態における拡散係数に関しては、溶解度と同様に温度・圧力と溶質さえ同じであればポリマーによらずほぼ同程度の拡散係数を示した。ただし、HDPEのみ約40%程度低い値となった。これは、用いたHDPEのみ分子量が他と比較して高く、溶融粘度の違いが影響したものと思われる。
    また、融点以下の温度では各コポリマーの結晶性の違いを反映し、溶解度は各コポリマーにより大きく異なる結果が得られた。そこで本研究では溶融状態で得られた溶解度を用いて融点以下ので溶解度を推算し、この値を用いて結晶化度を算出した。この結果、結晶性の高いHDPEでは溶質の溶解により結晶化度が上昇し、結晶性の低い他のポリマーでは溶質の溶解により結晶化度が低下していることが明らかになった。

    In this work, solubilities and diffusion coefficients were measured for nitrogen and ethylene in high-density polyethylene (HDPE) and two linear low-density polyethylenes (LLDPE) having different 1-hexene contents. The measurement was carried out using an apparatus based on the electricbalance method at temperatures of 333.2,353.2,403.2 and 433.2 K and at pressures up to 3.5 MPa. Moreover, measured solubilities and diffusion coefficients were correlated with Sanchez-Lacombe equation of state and Vrentas-Duda theory, respectively. From the investigations, the followings wree found :
    1. For the nitrogen - polymer systems, solubilities increased with increasing temperature, showing so-called reverse solubility that is common for gases with low critical temperatures. Degree of crystaliinity, that was determined from temperature dependence of Henry's constants, decreased with increasing temperature. Diffusion coefficients represented little concentration dependence. Temperature dependence of the diffusion coefficients was also small in the temperature range examined, where the diffusion coefficients increased about one ordr of magnitude with an increase in temperature.
    2. For the ethylene - polymer systems, solubilities decreased with increasing temperature, showing a usual temperature dependence. The solubilities of ethylene in amorphous regions of two LLDPE were almost the same despite different 1-hexene content. Ethylene showed about 7 times larger solubilities in the polymers thatn nitrogen. Diffusion coefficients of ethylene **vcaled remarkable temperature dependence. Concentration dependence of diffusion coefficients was also large at low temperatures.

    Sanchez-Lacombe状態式によりポリスチレン中のHFC134aの溶解度の推算を試みた。推算の際必要とされる純物質の特性パラメータは次の方法で決定した。ガスに関しては飽和物性(蒸気圧,飽和蒸気密度,飽和液密度)を最適に表現するように、ポリマーに関してはPVT測定を行って得られた比容積を最適に表現するように決定した。これらのパラメータを用い溶解度を推算したが、推算値は実験値を定性的には表現できるが、定量的な一致は得られなかった。そこで、Sanchez-Lacombe状態式に異種分子間相互作用パラメータを導入し相関を行った。異種分子間相互作用パラメータの温度依存性を考慮することにより、相関値と実験値は良好に一致した。

    Drying of silica alcogels using supercritical carbon dioxide was carried out at various conditions to investigate the optimal drying conditions for samples with different sizes. From the experiments it was found that a non-equilibrium interface that appeared in fluid phase in some gels, while the tem perature had a minor influence on the time. An increase in the sample thickness affected all stages of the drying process seriously, resulting in longer drying times. Hydrophobic modification of silanol groups on the gels was also performed in the middle of the supercritical drying process using three methylmethoxysilanes. The effects of the hydrophobic modification were evaluated by measuring water adsorption. The aerogel samples modified with methyltrimethoxysilane in the supercritical fluid phase showed higher hydrophobictiy than those modified in the liquid phase prior to the supercritical drying process.

    The adsorption equilibrium loadings of benzene, toluene, and acetone on two adsorbents, a BPL activated carbon and a high surface area activated carbon in the presence of supercritical carbon dioxide were measured at temperature of 313 K and pressures from 1 to 12 MPa. Loading of the pure adsorbates, carbon dioxide, benzene, toluene, and acetone on these activated carbons were also measured.
    At a constant partial pressure of the adsorbates, all adsorption loadings showed a maximum value at pure state and decreased with increasing pressure. On the same adsorbent benzene and toluene loadings shwed almost the same amount absorbed, while the loadings of acetone were lower than those of benzene and toluene. The adsorption loadings on the high surface area activated carbon were larger than those on the BPL activated carbon. However, pressure dependence was almost the same trend as that of BPL activated carbon. This may imply the effect of carbon dioxide adsorption over the amount of adsorbates and solvent power of carbon dioxide in fluid phase.
    Prediction method of adsorption amounts in the presence of supercritical fluid was examined in this work. An ideal adsorption solution theory (IAST) reported by Prausnitz et al.was used. Prediction values of IAST were in good agreement with experimental ones.
    Dynamics of adsorption of benzene dissolved in supercritical carbon dioxide on activated carbon were studied by analysis of breakthrough curves in the nonlinear region of the adsorption isotherm. Surface diffusion was found to be a main transport mechanism inside the adsorbent particles. Surface diffusion coefficients were similar to values reported by other investigators under lower pressures.

    1)成形体に欠陥が生じる原因の解明と最適操作条件の探索 シリカエアロゲルの製造法に関する工学的指針を得るために、試料にシリカアルコゲル,超臨界流体に二酸化炭素を用い、様々な大きさの試料に対して最適操作条件を探索した。加圧,加熱,流通,減圧,冷却の各段階での操作変数の値を種々変えて実験を行った結果、φ20×5mmの試料では3.5hで乾燥できたのに対し、φ26×20mmの試料ではその6倍の時間を要した。これは、試料が厚くなるとエタノールの拡散に時間がかかることと、試料内でのエタノールと二酸化炭素の濃度差が大きくなり試料に欠陥が生じやすくなるためであると思われ、これを避けるためには各段階での操作速度を小さくする必要があった。また、二酸化炭素の流通速度が大きくなるとセル内に二酸化炭素リッチ相とエタノールリッチ相の界面が発生し、これが欠陥の発生に影響していることが分かった。そこで、界面が発生しにくい実験条件を探索すると共に、状態方程式を用いて各成分の化学ポテンシャルを推算したところ、組成変化に対する化学ポテンシャルの勾配が小さい条件ほど界面が発生しやすいことが分かった。
    2)超臨界疏水化処理の検討 エアロゲルの透明性等の特性を劣化する原因となるシラノール基を除去するため、超臨界乾燥後に高圧下でシランカップリングを行うことを試みた。4種類の疏水化剤を用い、40℃,16MPaの条件で2時間反応させることにより疏水化処理を行い、疏水化の程度を評価するために水分吸着量の測定を行った。この結果、ヘキサメチルジシラザンを用いて処理を行った試料の水分吸着量は未処理試料のそれに比べてかなり小さく、超臨界流体存在下での疏水化処理が可能であることが分かった。しかしながら、他の3種類のメチル-メトキシ系の疏水化剤で処理した試料ではほとんど疏水化が行われておらず、今後、反応条件について検討する必要があると思われる。

    試料として超硬合金(10%のコバルトを含むタングステンカーバイド)の射出成形体を用い、超臨界二酸化炭素によるバインダーの除去について検討した。バインダーには低分子成分としてパラフィンワックスとステアリン酸,高分子成分としてポリエチレンとポリブチルメタクリレートを用い、バインダー添加量及び低分子成分と高分子成分の比を種々変えて試料を作成し、種々の条件でバインダーの除去(脱脂)を行った。1.脱脂率の検討結果 温度,圧力,時間等の脱脂条件及びバインダー組成と低分子成分の脱脂率の関係を検討した。その結果、温度及び圧力が高いほど脱脂率が高く、脱脂率と時間の関係はFickの拡散方程式で良好に相関できることが判明した。また、バインダー添加量が小さく、低分子成分の比が大きいほど脱脂率は高くなった。なお、従来の加熱脱脂法に比べて脱脂時間を大幅に短縮することが可能であった。
    2.脱脂体の健全性の検討結果 バインダー添加量が4wt%で全バインダー中の低分子成分の割合が60wt%程度の試料では、検討を行った全ての脱脂条件で欠陥の発生がなかった。このバインダー組成からはずれるほど欠陥の発生の頻度が高くなった。脱脂条件は脱脂体の健全性にはあまり影響がなかった。
    3.焼成体の強度の検討結果 健全性の良好な試料を焼成して3点曲げ強度を測定した。脱脂後の成形体中に残存しているバインダーの量が少ないほど焼成体の強度が向上し、従来法の製品の強度と同程度の値を得ることができた。
    以上より、超臨界脱脂法では適切なバインダーを探索することにより脱脂時間を大幅に短縮することができ、製品の強度も従来品と同程度であることが分かった。
