ABSTRACT:
A catalytic composite and its use in the fluidized catalytic cracking of hydrocarbons in the absence of added hydrogen. The composite comprises a binder material, a crystalline aluminosilicate, preferably a Y-type zeolite, and diatomaceous earth. Optional ingredients are kaolin, barium titanate and discrete particles of porous alumina. Absent from the composite is a supported catalytically active metal or metal oxide. The catalytic composite of the invention achieves higher gasoline production with lower coke production as compared to FCC catalysts with no diatomaceous earth content.
