Zeolites are crystalline alumino-silicate, and widely used as catalysts and adsorbents. MFI-type zeolite has fine pores within its crystals, the diameter of which is almost the same as the molecular size of benzene. Hence, the zeolite shows high molecular-sieving effect. When the zeolite is succeeded to be prepare in the shape of membrane, the membrane can enable to realize new separation and simultaneous reaction and separation with high performance. The main objective of this project is to development of MFI-type zeolite catalytic membrane, and to apply it to high separation and simultaneous reaction and separation processes. We obtained the following results through this research work :In fiscal year of 1999 :(1) MFI-type catalytic membrane was succeeded to prepared without any pin-holes by a new method, wellmixed hydrothermal synthesis.(2) When this membrane was applied to the pervaporation of concentrated acetic acid solutions, this membrane allowed only water to permeate in the r … More ange of the concentration of acetic acid from 30 to 98wt%.(3) We developed a new method, called "Catalytic Cracking of Silane (CCS) method", for decreasing the pore diameter of zeolite. The zeolite membrane treated by this method showed high separation factor of H_2 from mixture gases of H_2 and N_2 or O_2, about 100, as compared with 1.4 to 3 for a fresh zeolite membrane.In fiscal year of 2000 :Zeolites are crystalline alumino-silicate, and widely used as catalysts and adsorbents.

沸石是晶体铝硅酸盐，广泛用作催化剂和吸附剂。mfi型沸石晶体内部有细小的孔洞，孔洞的直径与苯的分子大小几乎相同。因此，分子筛具有较高的分子筛分效果。当沸石成功制备成膜状时，膜可以实现新的分离和高性能的同时反应分离。本项目主要目的是开发mfi型沸石催化膜，并将其应用于高分离和同时反应分离工艺。通过本研究工作，我们取得了以下成果：1999财年：(1)采用一种新的方法——混合水热合成法成功制备了无针孔的mfi型催化膜。(2)将该膜应用于浓乙酸溶液的渗透蒸发时，该膜只允许水在浓度为30% ~ 98%的范围内渗透。(3)提出了一种减小沸石孔径的新方法“硅烷催化裂化（CCS）法”。经该方法处理的沸石膜对H_2与N_2或O_2混合气体的分离系数较高，约为100，而新鲜沸石膜的分离系数为1.4 ~ 3。2000年会计年度：沸石是硅铝晶体，广泛用作催化剂和吸附剂。mfi型沸石晶体内部有细小的孔洞，孔洞的直径与苯的分子大小几乎相同。因此，分子筛具有较高的分子筛分效果。当沸石成功制备成膜状时，膜可以实现新的分离和高性能的同时反应分离。本项目主要目的是开发mfi型沸石催化膜，并将其应用于高分离和同时反应分离工艺。通过这项研究工作，我们得到了以下结果
