| description | Useful cracking catalysts and catalyst supports comprising silica supported on a boehmite-like surface are prepared by compositing particles of silica or hydrated silica with particles of porous boehmite and subjecting the resulting composite to high temperature steaming at a temperature of at least about 600°C for a time sufficient to disperse at least a portion of the silica over the boehmite surface as the boehmite converts to y-A1203. The silica wets, spreads out and reacts with the surface hydroxyl groups of the transforming boehmite. |
