Catalyst compositions and a process for making the same are disclosed. The composition finds application in the cracking of heavy hydrocarbon feedstock containing vanadium and other metal contaminants. It essentially comprises a crystalline zeolite, a metal trapping or passivating agent and an inorganic oxide matrix precursor and is characterized by minimum elution of an alkaline earth metal in the catalyst.

Catalyst compositions and process for making the same

The composition obtained by mixing a Y faujasite, having a phosphorus component into a water suspension of precursor of a porous matrix, and spray-drying said mixture, is a heavy hydrocarbon catalytic cracking catalyst which produces gasoline in high yield and is superior in thermally stability.

Hydrocarbon oil catalytic cracking catalyst compositions

A cracking catalyst for hydrocarbons with superior selectivity to gasoline production and greater metals tolerance comprising a porous inorganic oxide matrix composited with a crystalline aluminosilicate zeolite and a phosphorus-containing alumina in the form of small lumps.

Hydrocarbon catalytic cracking catalyst compositions and method therefor

A catalyst composition that is prepared by adding phosphorus to a hydrogel slurry of fibrous pseudoboehmite having a diameter of 0.05-0.3 .mu. and a length of 0.5 .mu. 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 .ANG. 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.

Hydrocarbon catalytic cracking catalyst compositions

In a catalytic cracking process for heavy oil which comprises contacting a heavy oil with a particulate mixture of a crystalline aluminosilicate-containing cracking catalyst particle and an alumina particle and/or a phosphorus-containing alumina particle mixed in the weight ratio of 80/20-20/80, under cracking conditions, metal contaminants contained in said feed oil are captured preferentially by said alumina particle and/or a phosporous-containing alumina particle, and the coexistent cracking catalyst is poisoned only to a reduced degree by metal contaminants.
