Abstract
A process for the production of a controlled supported zeolite membrane comprises: (a) forming a gel which is principally localised at the surface of a porous support by bringing it into contact, in succession, with two immiscible liquids which contain the agents necessary for formation of said gel, then (b) crystallising the zeolite from said gel and finally (c) eliminating the residual agents. The supported zeolite membranes obtained are advantageously used in continuous gas separation processes.
