Abstract
Hydrocarbon oils such as residual petroleum oils are efficiently deasphalted and demetallized with recovery of high quality asphalt by contact with a liquid mixture of at least two of the components selected from hydrogen sulfide, carbon dioxide and propane. The recovered deasphalted oil, which is characterized by reduced metal and sulfur content, may be used as charge stock to the fluid catalytic cracking process or to the hydrocracking process.
