Zusammenfassung:A feed stream is first processed in a hydrotreating reaction zone and then the effluent is separated into three fractions in a high pressure separation zone. Controlled portions of the middle and heavy boiling point range hydrocarbon fractions from this separation zone are recycled through a low conversion hydrocracking zone. The recycled hydrocarbons flow into a hydrocracking zone and the effluent of this zone flows into the hydrotreating reaction zone or the high pressure separation zone.
