Abstract
A process for treating zeolite membranes to improve their performance and to improve their coherence consists of forming a film of zeolite material on a porous support to form a zeolite membrane, contacting the membrane with tetraethylorthosilicate (TEOS), and reacting said TEOS with said zeolite membrane to form a supported membrane with open pores without defective pin holes. The process may further comprise pre-treatment of the porous support with a zeolite initiating agent, or post-treatment of the treated membrane with a silicic or polysilicic acid.
