Abstract:
1. A method for formulating a molecular sieve catalyst composition, the method comprising the steps of: (a) providing a synthesized molecular sieve having been recovered in the presence of a flocculant; (b) thermally treating the synthesized molecular sieve at a temperature from about 50° C. to about 250° C. and under other conditions sufficient to form a thermally treated synthesized molecular sieve having a first LOI less than 26% and a first micropore surface area; (c) aging the thermally treated synthesized molecular sieve for at least three months; (d) analyzing the aged, thermally treated molecular sieve to determine a second micropore surface area, wherein the second micropore surface area is not more than 3% lower than the first micropore surface area; and (e) combining the aged, thermally treated synthesized molecular sieve, a binder, and optionally a matrix material to produce an aged, formulated molecular sieve catalyst composition.
