Abstract: A HYDROCARBON CONVERSION CATALYST COMPOSITION COMPRISING A PHYSICAL ADMIXTURE OF A CONVENTIONAL, AMORPHOUS, SILICA-CONTAINING CRACKING CATALYSTS AND A CRYSTALLINE ALUMINO-SULICATE ZEOLITE SUSPENDED IN AN INORGANIC OXIDE GEL MATRIX. THE CATALYST IS PARTICULARLY USEFUL IN THE CATALYTIC CRACKING OF HYDROCARBON FEEDS. WHEN SO USED, THE CATALYST COMPOSITION IS MORE ACTIVE AND MORE SELECTIVE THAN WOULD BE PREDICTED FROM A CONSIDERATION OF ITS RELATIVE COMPOSITION.
