Membranes zeolite supported with structure type fau, their process of preparation and their applications.

摘要

The present invention relates to a membrane with a zeolitic fau type comprising a layer of zeolite crystals of fau type in the porosity of the surface of at least one of the faces chosen from a porous support, in which the ratio between the thickness of the selective layer of zeolite detected in the surface pores of a selected face of the support and the total thickness of the selective layer of the zeolite is at least 70% .elle also relates to methods of preparation and application of these membranes.
