Abstract
Preparation of the silica and alumina matrix components of a zeolite cracking catalyst while intimately mixing at a pH of 3.0 to about 4.5 results in a selective catalyst of high density and low pore volume. The coke produced during cracking emits lower amounts of sulfur during regeneration of tha catalyst translating to reduced sulfur oxide stack emissions.
