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.

Method for the preparation of catalyst composition for use in cracking

A catalyst composition suitable for catalytic cracking of a heavy hydrocarbon oil containing large amounts of metal contaminants is prepared by the steps of spray-drying an aqueous slurry containing a flash calcined alumina obtained by contacting an aluminum hydroxide prepared Bayer's process with a hot air of 350.degree.-700.degree. C. for 5 seconds or less, clay being predominantly composed of silica and alumina, a precursor of a siliceous inorganic oxide and a crystalline aluminosilicate; washing this particle until the alkali metal content therein is reduced to 1.0 wt % or less as oxide; and thereafter incorporating a rare earth component in the particle.

Method for preparing hydrocarbon catalytic cracking catalyst compositions

Impregnation of a crystalline aluminosilicate-containing cracking catalyst with a metal component of Group IVB enhances the catalytic activity, gasoline selectivity and thermal and hydrothermal stability of the catalyst, and further improves the catalyst's capacity of producing a high-octane gasoline.

Incorporation of a lithium component in a composition comprising a porous siliceous matrix and a crystalline aluminosilicate dispersed therein provides a hydrocarbon catalytic cracking catalyst having superior cracking activity and selectivity and also having a superior thermal and hydrothermal stability.
