Abstract:
A process for catalytic cracking of a hydrocarbon feedstock comprising contacting the feedstock with a catalyst composition comprising an amorphous mesoporous aluminophosphate material which comprises a solid aluminophosphate composition modified with at least one element selected from zirconium, cerium, lanthanum, manganese, cobalt, zinc and vanadium, wherein the mesoporous aluminophosphate material has a specific surface of at least 100 m2/g, an average pore diameter less than or equal to 100 Ã¥, a pore size distribution such that at least 50% of the pores have a pore diameter less than 100 Ã¥, wherein the catalyst composition further comprises a primary catalytically active cracking component.
