Cracking process using catalysts with carriers comprising silica supported on alumina. |
摘要 |
<p>Useful cracking catalysts and catalyst supports comprising silica supported on alumina are prepared by compositing particles of silica or silica precursor with particles of porous alumina and subjecting the resulting composite to high temperature steaming in a non-reducing environment at a temperature of at least about 500 DEG C for a time sufficient to disperse at least a portion of the silica over the alumina surface. The silica wets, spreads out and reactions with the surface hydroxyl groups of the alumina.</p> |
