An improved process and catalyst for economically converting carbo-metallic oils to lighter products. This process is practiced in accordance with effective metals management, carbon management and catalyst activity management combined with feed atomization-vaporization, efficient stripping of carbonaceous material from the coked catalyst, exothermic and endothermic removal of hydrocarbonaceous material to effectively maintain the RCC unit in heat balance. This reduced crude cracking process is practiced with a new and improved catalyst composition identified as RCCC-1 Special that is characterized by the following composition; at least 30 wt % rare earth exchanged ''Y'' faujasite crystalline zeolite with a silica to alumina ratio of at least 5 of a high lanthanum to cerium ratio and residual sodium content less than 0.30 wt %, is provided with a pore volume greater than 0.35 cc/gm. and comprises a clay matrix material that may or may not be acidic with pore size openings in the range of 500 to 2,000 angstroms. The RCCC-1 Special can contain metal promoters to catalyze the endothermic removal of coke and the partial removal of hydrogen present in the carbonaceous material with carbon dioxide. In addition, metal additives to passivate and immobilize vanadium are contemplated.
