Abstract
A catalytic composite, its method of manufacture and use is disclosed. The composite comprises a zeolitic crystalline aluminosilicate dispersed in a porous inorganic oxide carrier material comprising silica, alumina or zirconium and a constituent comprising the ions of one or more rare earths with the weight ratio on a volatile free basis of the rare earth ions to the carrier material being greater than 1.0:100.0. The method of manufacture of the composite comprises mixing a catalyst powder comprising the zeolite dispersed in a porous inorganic oxide carrier material with a solution of a salt of the rare earth, separating a filter cake from the slurry by a means not involving the washing of the filter cake and calcining the filter cake. The catalytic composite may be used in a process for cracking a hydrocarbon charge stock.
