ABSTRACT:
A process for the production of high quality lube oil blending stock from atmospheric fractionation residue and waste lubricants by means of contacting the waste lubricant with a hot hydrogen-rich gaseous stream to increase the temperature of this feed stream to vaporize at least a portion of the distillable hydrocarbonaceous compounds thereby producing a distillable hydrocarbonaceous stream which is immediately hydrogenated in an integrated hydrogenation zone. The vaporization of the waste oil is also conducted in the presence of an asphalt residue which is produced in the integrated process. The resulting effluent from the integrated hydrogenation zone provides at least one high quality lube oil blending stock stream.
