ABSTRACT:
There is provided a method for making large crystal size ZSM-5. This method involves the use of two organic cations, specifically tetrapropylammonium (TPA) and tetramethylammonium (TMA) cations, in the reaction mixture. This method further involves the use of a source of deliberately added alumina, such as aluminum sulfate, in the reaction mixture.
