This patent describes a hydrocracking process. It comprises passing a feed stream which comprises an admixture of hydrocarbons boiling above 240 degrees Centigrade and hydrogen through a hydrocracking reaction zone maintained at hydrocracking conditions and producing a mixed-phase hydrocracking reaction zone effluent stream; separating the mixed-phase hydrocracking reaction zone effluent stream into a first vapor stream, which comprises hydrogen, light hydrocarbons and distillate hydrocarbons, and a first liquid stream, which comprises distillate hydrocarbons; forming a second vapor stream and a second liquid, stream by partially condensing the first vapor stream, with the second liquid stream comprising distillate hydrocarbons and having a lower average boiling point than the first liquid stream; passing the second liquid stream and added hydrogen through a hydrogenation reaction zone maintained at hydrogenation conditions and producing a hydrogenation zone effluent stream; and, passing distillate hydrocarbons present in the hydrogenation zone effluent stream and the first liquid stream into a fractionation zone, and recovering a hydrocracking zone product stream.
