Abstract:
    A catalyst composition that is prepared by adding phosphorus to a hydrogel slurry of fibrous pseudoboehmite having a diameter of 0.05-0.3 mum and a length of 0.5 mum or more, mixing a crystalline aluminosilicate zeolite and a clay mineral therewith, spray drying this mixture and calcining, and has a total pore volume (PV) of 0.3-0.7 cc/g, a volume (PVa) occupied by pores whose diameter is 600 ANGSTROM or less of 0.3-0.7 cc/g and a PVb/PVa ratio where PV-PVa-PVb of 0.5-2.0, displays superior activity, selectivity and metals tolerance when used in the fluid cat-cracking of heavy hydrocarbon oils, in particular residual oils.
