Abstract

A composite mixture of siliceous cracking catalyst and a zeolite is formed in water and then is washed with an aqueous solution of an ammonium salt to reduce the alkali-metal content of the zeolite before drying. Various filterings, washings slurryings and spray dryings may be performed on the composite before the ammonium treatment. The zeolite has the general formula xR2O: ym2/n O:Al2O3 : 3.5-7SiO2 : O-9H2O where x is 0.1-1; y is O to (1-x) m is a cation other than alkali-metal of valency n and R is an alkali metal cation. The siliceous catalyst may be silicon/magnesia, silicon/zirconia, silica/alumina, silica/alumina/zirconia or silica/magnesia/alumina or an acidified clay. Unit cell sizes surface areas and pore sizes are mentioned.
