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.degree. 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.degree. F.

Abstract: A process for economically converting carbo-metallic oils to lighter products. The carbo-metallic oils contain 650.degree. F.+ material which is characterized by a carbon residue on pyrolysis of at least about 1 and a Nickel Equivalents of heavy metals content of at least about 4 parts per million. This process comprises flowing the carbo-metallic oil together with particulate cracking catalyst through a progressive flow type reactor having an elongated reaction chamber, which is at least in part vertical or inclined, for a predetermined vapor riser residence time in the range of about 0.5 to about 10 seconds, at a temperature of about 900.degree. to about 1400.degree. F., and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 40% to 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0.

Abstract: A process is disclosed for upgrading a hydrocarbon oil feed having a significant content of metals, especially vanadium, to provide a higher grade of oil products by contacting the feed under sorbing conditions in an upgrading zone with a high surface area, high pore volume sorbent material containing an added alkaline metal to neutralize acidic cracking sites. Upgrading conditions are such that coke and metals are deposited on the sorbent in the upgrading zone. Coked sorbent is regenerated by contact with an oxygen containing gas under regeneration conditions to remove the coke, and regenerated sorbent is recycled to the upgrading zone for contact with fresh feed. The added alkaline metal is present on the sorbent in an amount sufficient to neutralize substantially all of the acidic cracking sites and provide a sorbent material having a MAT relative activity in the range of about 0 to about 1 percent.

Abstract: A process is disclosed for decarbonization-demetallization of a poor quality residual oil feed boiling above about 650.degree. F. and comprising substantial Conradson carbon components to provide a higher grade of oil feed by contacting the poor quality oil feed with sorbent particle material containing one or more metal additives selected to catalyze the endothermic removal of coke with CO.sub.2. Sorbent decarbonization conditions are selected so that substantial quantities of carbonaceous material and metals are deposited on the sorbent in the decarbonizing zone. Sorbent material with metals and hydrocarbonaceous deposits is regenerated in the presence of an oxygen and carbon dioxide containing gas streams in separate sorbent regeneration zones at a temperature sufficiently elevated to remove residual coke to a desired low level. Regenerated sorbent particle material at an elevated temperature below about 1500.degree. F.
