MFI-type zeolitic membranes were prepared by a vapor-phase transport (VPT) method on porous alpha-alumina flat disks. Single-and mixed-gas permeation measurements of butane isomers were performed in the temperature range of 300-375 K.The separation factor was always greater than the ideal selectivity. This result is explained by the preferential adsorption of n-butane on MFI in the binary system.The pervaporation tests for xylene isomers were performed at 303 K.p-Xylene was the most permeable component in the unary system. In the permeation measurements of a binary mixture of p-xylene/m-xylene and a ternary mixture of p-xylene/m-xylene/o-xylene, p-xylene predominantly permeated in the early stage, and then, the Aux of p-xylene decreased gradually and finally became lower than that of the other xylene isomers. The adsorption of m-xylene in the pores of MFI seemed to block the permeation of p-xylene.

采用气相传输(VPT)方法在多孔α-氧化铝平板上制备了MFI型分子筛膜。在300-375K温度范围内对丁烷异构体进行了单气相渗透和混合气相渗透测量，分离因子总是大于理想的选择性。这一结果是由于正丁烷在MFI上的优先吸附所致。二甲苯异构体的渗透汽化实验是在303K下进行的。对二甲苯是一元体系中最具渗透性的组分。在对二甲苯/间二甲苯二元混合物和对二甲苯/间二甲苯/邻二甲苯三元混合物的渗透测量中，对二甲苯的AUX在早期以渗透为主，然后逐渐降低，最后低于其他二甲苯异构体。间二甲苯在MFI孔内的吸附似乎阻碍了对二甲苯的渗透。
