ABSTRACT:
A hydrocracking process of improved flexibility comprises three hydroprocessing stages and a fractionating zone such that the effluent from the first hydroprocessing stage is fractionated into a first fraction consisting of gasoline and lower boiling components, a second fraction, the residuum, having a normal boiling point greater than about 700.degree. F. (370.degree. C.), and a third fraction, the middle and heavy distillate, consisting of the remainder of the effluent of the first hydroprocessing stage. The second fraction undergoes hydrocracking in a second hydroprocessing stage with recycle of the effluent from said second hydroprocessing stage to the fractionation zone, and the third fraction undergoes hydrocracking in a third hydrocracking stage.
