Abstract
High boiling hydrocarbon materials are hydrocracked in a multiple stage process having ebullating catalyst bed hydrogenation reactor stages in series. Between the hydrogenation reactors is an interstage separator/stripper to separate a vapor phase and to strip the liquid phase with hydrogen to produce a heavier, more concentrated liquid phase as the feed to the next ebullating bed reactor stage in the series. The feed to the second stage may be blended with an aromatic solvent and/or a portion of the high boiling hydrocarbon feedstock.
