CRYSTALLINE ALUMINOSILICATES: UZM-13, UZM-17, UZM-19 AND UZM-25

摘要

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.
