项目摘要

The concept of a fining-type membrane is used to design: a membrane for vapor permeation and pervaporation. The filling-type membrane is composed of two materials : the porous substrate and the filling polymer that fills the pores of the substrate. The fining polymer exhibits permselectivity due to the solubility difference, and the porous substrate matrix suppress the swelling of the filling polymer due to its mechanical strength. These types of membrane showed good separation performances for liquid or vapor mixtures. When the filling polymer solubility, suppression effect of membrane swelling due to the substrate and solvent diffusivity in the filling polymer can be qualitatively predicted by model simulation, filling type membrane concept and the prediction method enable us to choose a suitable membrane material for a separation mixture. A model has been previously developed to calculate solvent permeation rate through the fining-type membrane. This model succeeded in estimating pe … More rmeability of organics through rubbery filling-type membranes without any adjustable parameters, however, the prediction somewhat deviated from experimental values. The deviation came from solubility prediction for rubbery polymers, and diffusivity prediction for glassy polymers cannot be estimated by the Free-Volume Theory previously used. In this study, solvent solubility is predicted by the GCLF-EOS model, and compared with the previously used UNIFAC-FV model. Also, the prediction model was extended to glassy polymer case using a modified Free Volume model we are proposing for a glassy polymer. For various polymer systems studied, the GCLF-EOS model provides better accuracy, and this is attributed to the correct prediction of the effect of excess volume on solubility. The diffusivity estimation in glassy polymer was predicted using the model proposed, and the calculation well agreed with experimental results. The flux of benzene, toluene and ethylbenzene is measured by vapor permeation experiments through filling-type acrylate or methacrylate membranes, and the prediction from this approach agrees well with the vapor permeation experiments.

精细化膜的概念被用于设计:一种蒸汽渗透和渗透蒸发的膜。填充型膜由两种材料组成:多孔基板和填充基板孔隙的填充聚合物。由于溶解度的差异,细化聚合物表现出过氧化物选择性,多孔基质由于其机械强度抑制填充聚合物的膨胀。这些类型的膜对液体或蒸汽混合物具有良好的分离性能。当填充聚合物的溶解度、底物对膜溶胀的抑制作用以及填充聚合物中溶剂的扩散率均可通过模型模拟进行定性预测,填充型膜的概念和预测方法使我们能够为分离混合物选择合适的膜材料。以前已经建立了一个模型来计算溶剂通过精细化型膜的渗透速率。该模型在不需要任何可调参数的情况下,成功地预测了有机物质通过橡胶填充型膜的渗透性,但预测结果与实验值有一定偏差。这种偏差来自于橡胶聚合物的溶解度预测,而玻璃聚合物的扩散率预测不能用以前使用的自由体积理论来估计。本研究采用GCLF-EOS模型预测溶剂溶解度,并与先前使用的unifacf - fv模型进行比较。同时,利用改进的自由体积模型,将预测模型扩展到玻璃聚合物的情况。对于所研究的各种聚合物体系,GCLF-EOS模型提供了更好的准确性,这归功于对过量体积对溶解度的影响的正确预测。利用该模型对玻璃聚合物中的扩散系数进行了预测,计算结果与实验结果吻合较好。采用填充型丙烯酸酯或甲基丙烯酸酯膜进行气相渗透实验,测定了苯、甲苯和乙苯的通量,所得结果与气相渗透实验结果吻合较好。少
