摘要： Useful cracking catalysts and catalyst supports comprising mixtures of tungsten oxide and silica supported on alumina are prepared by forming a composite of a mixture of (a) particles of tungsten oxide or one or more suitable tungsten oxide precursors, (b) particles of silica and (c) particles of porous alumina and steaming said composite at a temperature of at least about 500.degree. C. in a non-reducing environment for a time sufficient for at least a portion of the tungsten oxide and silica to disperse over the alumina surface. The mixture of silica and tungsten oxide wets, spreads out and reacts with the surface hydroxyl groups of the alumina.
