Abstract
A fluid catalytic cracking catalyst is provided with a high porosity by in-situ crystallizing an aluminosilicate zeolite from a reactive microsphere comprising metakaolin and hydrous kaolin. Any calcination of the reactive microsphere before reaction with a zeolite-forming solution is done at low temperatures so as to ensure the hydrous kaolin is not converted to metakaolin.
