ABSTRACT:
Useful cracking catalysts and catalyst supports comprising a mixture of tungsten oxide and silica supported on a boehmite-like surface which, in turn, is supported on alumina are prepared by forming a composite of particles of (a) tungsten oxide, (b) silica and (c) boehmite and subjecting the composite to steaming at a temperature of at least about 500.degree. C. During the steaming, the tungsten oxide and silica react with the surface of the boehmite as the boehmite converts to alumina.
