FAU-structural-type supported zeolite membranes, their process for preparation and their applications

摘要

The invention relates to a FAU-type zeolite membrane that comprises a FAU-type zeolite crystal layer incorporated in the surface porosity of at least one selected face of a porous substrate, in which the ratio between the thickness of said zeolite layer incorporated in the surface porosity of said selected face of the substrate and the total thickness of said zeolite layer is at least 70%. It also relates to processes for preparation and application of these membranes.
