Zusammenfassung:	The present invention is directed toward a new zeolite composition having coated thereon a mesoporous growth enhancing layer and a layer of zeolite crystals on said mesoporous growth enhancing layer, and wherein said mesoporous 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, colloidal metal and metal oxide, and wherein said mesoporous growth enhancing layer has interstices of about 20 to about 2000 ANGSTROM , and wherein said zeolite layer is a polycrystalline layer of oriented crystals with similar habit wherein 99,9 % of said zeolite crystals have at least one point between adjacent crystals that is
