ABSTRACT:
A process for the simultaneous production of lubricating blending stocks by means of hydrocracking a hydrocarbon feedstock in a first hydrocracking zone to convert at least a portion of the heavy hydrocarbon feedstock to produce an effluent stream containing lube oil boiling range hydrocarbons. One portion of the effluent stream is directly removed from the first hydrocracking zone to produce high quality lube oil blending stocks. Another portion of the effluent stream from the first hydrocracking zone is directly introduced into a second hydrocracking zone without intermediate separation. The second hydrocracking zone is utilized to further crack the feed to produce motor fuel.
