Abstract

The present invention is directed toward a new zeo-lite composition having coated thereon a mesoporous growth enhancing layer and a layer of zeolite crystals on said meso-porous growth enhancing layer, and wherein said meso-porous growth enhancing layer comprises nanocrystalline or colloidal sized zeolites, nanocrystalline or colloidal zeolite and metal oxide, or nanocrystalline or colloidal zeolite and colloidal metal, or nanocrystalline or colloidal zeolite col-loidal metal and metal oxide, and wherein said mesoporous growth enhancing layer has interstices of about 20 to about 2000 .ANG., and wherein said zeolite layer s a polycrystalline layer of oriented crystals with similar habit wherein 99,9 %
of said zeolite crystals have at least one point between adja-cent crystals that is 20 .ANG.. The invention is further directed to a process of producing and using the composition.
