CA 2193258

The applicant has discovered a new zeolite containing composition and a process for preparing the same. The composition is unique in that the zeolite crystals making up one layer of the composition pack in a manner such that the composition is essentially continuous with no large scale voids even when the zeolite layer is < 10 µm thick. Thus, the present invention is directed toward a composition comprised of a porous substrate and a layer of zeolite crystals wherein said layer of zeolite crystals is a polycrystalline layer with at least 99 % of said zeolite crystals having at least one point between adjacent crystals that is <= 20 .ANG. and wherein at least 90 % of said crystals have widths of from about 0.2 to about 100 microns (preferably about 2 to about 50 microns) and wherein at least 75 % of said crystals have a thickness of within 20 % of the average crystal thickness. Preferably the composition has at most 1 Volume % voids in the zeolite layer. Use of the composition is also described.

Nouvelle composition contenant une zéolite et procédé de production de ladite composition. Cette composition est unique en son genre en cela que les cristaux de zéolite constituant une couche de la composition s'assemblent d'une manière telle que ladite composition est essentiellement continue et ne comporte pas de vides importants, même lorsque la couche de zéolite est d'une épaisseur < 10 µm. En conséquence, la présente invention concerne une composition constituée d'un substrat poreux et d'une couche de cristaux de zéolite. Ladite couche de cristaux de zéolite est une couche polycristalline, au moins 99 % desdits cristaux de zéolite ayant au moins un point entre des cristaux adjacents qui est ? 20 .ANG., au moins 90 % desdits cristaux ayant des largeurs d'environ 0,2 à environ 100 microns (de préférence d'environ 2 à environ 50 microns) et au moins 75 % desdits cristaux ayant une épaisseur située dans les 20 % de l'épaisseur moyenne des cristaux. De préférence, ladite composition possède au plus des vides de 1 % en volume dans la couche de zéolite. L'utilisation de ladite composition est également décrite.
