ABSTRACT:
A method of increasing the activity and selectivity of a regenerated used FCC catalytic composite comprising a zeolitic crystalline aluminosilicate dispersed in a porous inorganic oxide matrix, the resultant composite and a cracking process utilizing the resultant composite. 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 then evaporating off the water of the slurry.
