Title:
A METHOD FOR RAPIDLY SYNTHESIZING A SILICOALUMINOPHOSPHATE SAPO-34 MOLECULAR SIEVE
Document Type and Number:
WIPO Patent Application WO/2008/022532
Kind Code:
A1
Abstract:
Provided is a method for rapidly synthesizing a silicoaluminophosphate SAPO-34 molecular sieve, wherein triethylamine and/or diethylamine are/is used as templating agents, an organic amine accelerator is added to the initial gel for synthesis at the same time, and the gel mixture is optionally subjected to aging treatment. The method could give SAPO-34 molecular sieves with high crystallization degree in a relative short crystallization period. The SAPO-34 molecular sieve catalysts synthesized by the method can be used in the MTO or DTO reaction, the selectivity of C2~C3 olefins in the product could be up to about 90%.
