Patent

CA 2539677

A series of crystalline aluminosilicate compositions have been prepared. These compositions have a layered structure and are identified as UZM- 13, UZM- 17 and UZM- 19. Upon calcination at a temperature of 400 ~C to 600 ~C, these compositions form a microporous crystalline zeolite with a three dimensional framework which has been identified as UZM-25. A process for preparing all these compositions and processes for using these compositions are also disclosed.

L'invention porte sur la préparation d'une série de compositions d'aluminosilicates cristallins. Ces compositions ont une structure en couches et sont identifiées sous les appellations UZM- 13, UZM- 17 et UZM- 19. Lors de la calcination à une température comprise entre 400 ·C et 600 ·C, ces compositions forment un zoolite cristallin microporeux à structure tridimensionnelle qui a été identifié sous l'appellation UZM-25. L'invention porte également sur un procédé de préparation de toutes ces compositions et sur leurs procédés d'utilisation.
