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分子筛膜，甲醇在甲基叔丁基醚上的渗透汽化（PV）和苯在环己烷（Cx）和正己烷（Hx）上的蒸气渗透（VP）分别表现为甲醇和Bz的优先吸附。由不对称聚酰亚胺中空纤维膜制备的碳化膜通过分子筛分得到了优异的丙烯/丙烷和1,3 -丁二烯/正丁烷性能。以磺酸基悬垂的酚醛树脂为原料制备的复合碳化膜，在烃类混合物中具有PV和VP的潜力。研究了橡胶和玻璃聚合物膜对Bz/Cx和Bz/Hx混合物的吸附和扩散行为。仅在玻璃状聚合物中观察到竞争吸附和共存组分对扩散系数的耦合效应。同位素-瞬态渗透实验可用于测量PV稳态下组分的扩散系数。此外，还制备了含硫环的聚酰亚胺、与膦酸基团悬垂的甲基丙烯酸酯共聚物、芳香超支化聚酰亚胺或星形聚酰亚胺作为碳氢化合物混合物PV的优良膜材料。
