ABSTRACT:
A process is disclosed for converting a heavy hydrocarbon oil feedstock to produce a high yield of lower-boiling hydrocarbons, wherein a residuum fraction of the effluent from a hydrogen donor diluent hydrocracking reactor is deasphalted using a low-boiling solvent and at least the highest-boiling fraction of the deasphalted oil is recycled to the hydrogen diluent hydrocracking zone.
