Abstract
Preparation of fluid catalytic cracking catalysts is improved by incorporating a viscosity-reducing agent, having the general formula of Al.sub.2 (OH).sub.5 NO.sub.3, in the aqueous slurry containing the catalyst components of zeolite, clay, aluminous binder, and a silica source, prior to drying of the slurry. The viscosity-reducing additive allows an increase in the solids content of the aqueous slurry and thus improves the efficiency of the drying operation.
