Title: Endothermic removal of coke deposited on catalytic materials during carbo-metallic oil conversion

Abstract

A process is disclosed for the conversion of high boiling oil feeds having a significant level of Conradson carbon components and metals to form lighter oil products by contacting the feed under catalytic conversion conditions with a catalyst containing one of a select group of metal additives to catalyze the endothermic removal of carbon with CO/sub 2/. Conversion conditions are such that hydrocarbonaceous material and metals are deposited to deactivate the catalyst in the conversion zone. Deactivated catalyst is partially regenerated in the presence of carbon dioxide containing gas before or after oxygen regeneration at a temperature below 1600/sup 0/ F. to provide a regenerated catalyst which is recycled to the conversion zone for further contact with fresh feed. The metal additive is present on the catalyst in an amount sufficient to catalyze the endothermic removal of carbonaceous material in the presence of a carbon dioxide rich gas at regeneration temperature below 1500/sup 0/ F. The catalyst composition comprises a crystalline aluminosilicate dispersed in a solid matrix material and containing one or more of the metal additives. Metal additive may be introduced into the catalyst during the conversion process or during catalyst manufacture. Metal additives include water soluble inorganic metalmore » salts, hydrocarbon soluble organo-metallic compounds of the select group of metals, and metal contaminants found in a high boiling residual oil feed.« less
