Catalysts for use in cracking, comprising a zeolite and a matrix, are prepared by a procedure which includes phosphate treatment of the zeolite, optionally of matrix constituents also. The zeolite may be of large, intermediate or small pore size. The preferred procedure involves mixing the zeolite with aqueous phosphate solution, combining this mixture with matrix precursor to form a slurry, and spray-drying the slurry. Catalysts so prepared are of enhanced attrition resistance, and in certain embodiments also provide improved selectivity and/or product quality in use. They are well suited for cracking heavy feeds such as resid.
