ABSTRACT:
A method is provided for effectively tailoring the catalytic activity of synthetic crystalline zeolites. The method involves synthesizing the zeolite from a reaction mixture containing a source of bulky organic cations, contacting the synthesized zeolite with hydrogen fluoride solution, calcining the hydrogen fluoride solution contacted zeolite, contacting the calcined zeolite with an ammonium exchange solution, and then calcining the ammonium exchange solution contacted zeolite.
