Process for fluid catalytic cracking using catalysts containing an alumina-on-silica component.

摘要

Disclosed is a fluid catalytic cracking process using a catalyst composite comprised of an alumina-on-silica material, an inorganic refractory oxide, and optionally a zeolite material. The alumina-on-silica material is comprised of silica particles with surface bound aluminum groups chemically bonded to the silica surface through surface oxygen atoms, which material is dispersed in a matrix of a refractory oxide.
