NaY zeolite membranes were successfully prepared and showed high performance of pervaporation (PV) of methanol over methyl tert-butyl ether and of vapor permeation (VP) of benzene (Bz) over cyclohexane (Cx) and n-hexane (Hx) due to preferential adsorption of methanol and Bz, respectively.Carbonized membranes derived from an asymmetric polyimide hollow fiber membrane showed excellent performance of propylene/propane and 1, 3-butadiene/n-butane due to molecular sieving. Composite carbonized membranes derived from phenolic resins with pendant sulfonic acid group have potential for PV and VP of hydrocarbon mixtures.Sorption and diffusion behavior to Bz/Cx and Bz/Hx mixtures was investigated for rubbery and glassy polymer membranes. Competitive sorption and coupling effect of the coexisting component on diffusion coefficient were observed only for the glassy polymers. Isotopic-transient permeation experiments were useful to measure diffusion coefficient of the component under steady state of PV.Thianthrene-ring-containing polyimides, copoly (methacrylate) with pendant phosphonate groups, aromatic hyperbranced or star-like polyimides were also prepared as noble membrane materials for PV of hydrocarbon mixtures.

成功制备了nay沸石膜，并显示出苯基丁基甲烷上甲醇的高性能（PV）在环己烷（CX）和N-甲苯烷（HX）上的苯丁基丁基和蒸气渗透（VP）的高性能（VP）。甲醇和BZ的吸附分别是源自不对称的聚酰亚胺空心纤维膜的碳化膜，其丙烯/丙烷和1、3-丁二烯/N-丁烷的表现出色，这是由于分子筛分而引起的。源自苯磺酸磺酸的酚类树脂的复合碳化膜对于碳氢化合物混合物的PV和VP具有潜力。对BZ/CX和BZ/HX混合物进行了吸附和扩散行为，用于橡胶和玻璃状聚合物膜。仅在玻璃聚合物中观察到共存成分对扩散系数的竞争吸附和耦合效应。同位素 - 交易剂渗透实验对于测量稳态下的组件的扩散系数是有用的用于烃混合物的PV。
