Abstract

Highly stable FAU-type zeolite membrane for the separation of isopropanol (IPA)-water mixture by pervaporation is described. FAU membrane showed high water permselectivity and permeance. Comparison of FAU membrane with a conventional LTA-type zeolite membrane revealed superior stability of FAU zeolite membrane in a mixture containing a large water content.

摘要

描述了一种用于通过渗透蒸发分离异丙醇（IPA）-水混合物的高度稳定的FAU型沸石膜。FAU膜表现出高的水渗透选择性和渗透率。将FAU膜与传统的LTA型沸石膜进行比较，结果表明FAU沸石膜在含水量高的混合物中具有优异的稳定性。
