Production of fluid catalytic cracking catalysts

摘要

Preparation of fluid catalytic cracking catalysts is improved by incorporating a viscosity-reducing agent, having the general formula of Al2(OH)5NO3, 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.
