A catalyst composition for the catalytic cracking of hydrocarbons, which comprises:
- a porous inorganic oxide matrix containing mixed therein (1) particles of crystalline aluminosilicate zeolite and (2) alumina particles having a particle diameter of from 15 to 60 .mu.m and impregnated with a phosphorus component.
A catalyst composition for the catalytic cracking of hydrocarbons, which comprises:
- a porous inorganic oxide matrix containing mixed therein (1) particles of crystalline aluminosilicate zeolite and (2) alumina particles having a particle diameter of from 15 to 60 .mu.m and impregnated with (a) a phosphorus component and (b) at least one auxiliary component selected from the group consisting of alkaline earth metals, rare earth metals, antimony, bismuth, boron, manganese and tin.
A method for preparing a catalyst composition for the catalytic cracking of hydrocarbons, which comprises the steps of mixing (a) alumina particles having a particle diameter of from 15 to 60 .mu.m and impregnated with a phosphorus compound, with (b) particles of crystalline aluminosilicate zeolite and with (c) an aqueous slurry of a precursor of a porous inorganic oxide matrix to form a catalyst slurry;
