CATALYST MANUFACTURE Abstract Catalysts and catalyst supports are prepared by forming and drying, preferably spray-drying, an aqueous slurry of inorganic solids such as zeolites, clay, silica, alumina, and silica-alumina gel, and aluminum chlorhydrol to obtain particulate composites. The particulate composites are then reacted with ammonia in the absence of free liquid water to convert the aluminum chlorhydrol into a cohesive binder. The ammonia-reacted composites may then be washed, ion exchanged and thermally activated to obtain active attrition resistant catalysts and catalyst components.
