ABSTRACT:
Catalytic compositions which comprise alumina bound spinel and/or spinel-mullite mixtures having an alkali metal content of below about 0.50 weight percent, preferably below about 0.10. The compositions are obtained by calcining a caustic leaching preformed particulate composites of clay and alumina sol, preferably chlorhydrol. The catalysts are particularly useful for the catalytic cracking of heavy hydrocarbon feedstocks to obtain gasoline and light cycle oil. When used for cracking feedstocks high in vanadium content these compositions may contain added alkaline earth oxide in order to passivate the vanadium.
