ABSTRACT A process is provided for the simultaneous and continuous hydrocraking of two feed stocks for the production of maximum hydrocarbon distillate and optimum lube oil base stock. The first feed stock, preferably deasphalted crude resid, is reacted in a first hydrocraking reaction zone to produce a first principally vaporous phase and a first principally liquid phase. The second feed stock and the first vaporous phase are reacted in a second hydrocracking reaction zone to produce a second principally vaporous phase and a second principally liquid phase. At least a portion of the first principally liquid phase and at least a portion of the second principally liquid phase are recycled to the first hydrocracking reaction zone. At least a further portion of the first principally liquid phase and at least a further portion of the second principally liquid phase are separated to recover the hydrocarbon distillate and the lube oil base stock.
