Abstract
A feed stream is first processed in a hydrotreating reaction zone and then the effluent is separated into three fractions in an augmented first high pressure separator. Controlled portions of the middle and heavy boiling point range hydrocarbon fractions from this separator are recycled through a low conversion hydrocracking zone, while the remaining portions of these two fractions are passed into a second high pressure separator for recovery. The recycled hydrocarbons flow into a hydrocracking zone and the effluent of this zone flows into the hydrotreating reaction zone.
