Patent

CA 2468767

The invention relates to a porous crystalline material which, in the calcined state, has composition: X2O3: n YO2: m ZO2, wherein: X represents a trivalent element; Z represents Ge; and Y represents at least one tetravalent element other than Ge. Furthermore, in the chemical composition, (n + m) is equal to at least 5 and the Y/Z ratio is equal to at least 1. Moreover, in the calcined state, said material has an X-ray diffraction pattern which coincides substantially with table 1.

L'invention a trait à un matériau cristallin poreux qui, en état calciné, présente la composition suivante : n X¿2?0¿3?: n Y0¿2?: m Z0¿2?, dans laquelle X représente un élément trivalent, Z représente Ge, Y représente au moins un élément tetravalent différent à Ge, et dans laquelle (n + m) vaut au moins 5, et la relation Y/Z vaut au moins 1. Ladite composition contient, sous forme calcinée, un patron de diffraction de rayons X qui coïncide sensiblement avec le tableau 1.
