Abstract
A FCC catalyst having improved coke selectivity and greater catalyst strength, and a FCC process for converting hydrocarbon feedstocks to lower boiling products. The catalyst comprises a crystalline aluminosilicate zeolite, gibbsite, and a silica matrix prepared from at least one of a silica sol made by an ion-exchange process and an acidic silica sol prepared by mixing sodium silicate, an acid and an aluminum salt of an acid.
