<p>A process for the production of high attrition resistant inorganic compositions is provided. The formation of highly attrition resistant compositions is accomplished by forming a slurry of inorganic components, a binder, and optionally clay and matrix materials, milling the slurry, and cooling the milled slurry to a temperature below 17° C., preferably below 10° C. The cooled slurry is subjected to spray-drying, and optionally calcining and/or washing, to provide highly attrition resistant inorganic particles. Catalytic cracking catalysts formed by the process are also disclosed.</p> |
