<p>CATALYSTS AND CATALYST SUPPORTS Catalysts and catalyst supports which comprise solid inorganic oxides, such as crystalline zeolites, clay and/or inorganic gels, combined with an acid reacted metakaolin binder. The compositions may be spray dried and calcined to obtain dense, attrition resistant fluid cracking catalysts or used in the preparation of formed catalyst supports.</p> |
