Abstract

This invention comprises a process for cracking a hydrocarbon charge stock using a used FCC catalytic composite comprising a zeolitic crystalline aluminosilicate dispersed in a porous inorganic matrix. Particles of zeolitic crystalline aluminosilicate having diameters less than the diameters of the pores of the composite are impregnated into the composite preferably by contacting the composite with an aqueous slurry of the particles and the evaporating off the water of the slurry.
