PROCESS FOR PREPARING ATTRITION RESISTANT MOLECULAR SIEVE CATALYSTS AND THEIR USE FOR OXYGENATE TO OLEFINS CONVERSION

摘要

This invention is directed to a hardened molecular sieve catalyst composition, a method of making the composition and a method of using the composition. The catalyst composition is made by mixing together molecular sieve, liquid, and an effective hardening amount of a dried molecular sieve catalyst to form a slurry. The slurry is dried, and then calcined to form the hardened molecular sieve catalyst composition. The hardened molecular sieve catalyst is highly attrition resistant.
