ABSTRACT:
Catalytic cracking catalysts are combined with a rare-earth, preferably lanthanum-containing catalyst/additive to enhance the cracking activity and selectivity in the presence of nickel and vanadia (Ni & V). The preferred additives comprise lanthanum, neodynium oxide and/or oxychloride dispersed in a clay/alumina matrix, wherein the alumina is derived from an aluminum hydroxychloride sol.
