ABSTRACT:
A process for the production of distillate hydrocarbon 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 a vacuum fractionation residue which is produced in the integrated process. The resulting effluent from the integrated hydrogenation zone and a distillable hydrocarbon stream recovered from the atmospheric fraction residue is catalytically converted to produce lower molecular weight hydrocarbon compounds.
