ABSTRACT:
A hydrocracking process wherein a liquid phase stream comprising a hydrocarbonaceous feedstock and a liquid phase effluent from a hydrocracking zone and a sufficiently low hydrogen concentration to maintain a liquid phase continuous system into a hydrotreating zone. A portion of the effluent from the hydrotreating zone comprising unconverted hydrocarbons is introduced into the hydrocracking zone with a sufficiently low hydrogen concentration to maintain a liquid phase continuous system.
