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%.
