Abstract
A feed stream is processed in a hydrotreating reaction zone and then the hydrotreating effluent is separated into two fractions in a first high pressure separator. The vapor fraction is passed into a second high pressure separator. A controlled portion of the liquid fraction from the first high pressure separator and the liquid from the second high pressure separator are passed into a hydrocracking zone. The remaining portion of the liquid from the first high pressure separator is passed into the product recovery zone.
