Patent number: 9028674Abstract: A process for upgrading residuum hydrocarbons including: feeding pitch, hydrogen, and a partially spent catalyst recovered from a hydrocracking reactor to an ebullated bed pitch hydrocracking reactor; contacting the pitch, hydrogen, and the catalyst in the ebullated bed pitch hydrocracking reactor at reaction conditions of temperature and pressure sufficient to convert at least a portion of the pitch to distillate hydrocarbons; and separating the distillate hydrocarbons from the catalyst. In some embodiments, the process may include selecting the ebullated bed pitch hydrocracking reactor reaction conditions to be at or below the level where sediment formation would otherwise become excessive and prevent continuity of operations.Type: GrantFiled: January 17, 2013Date of Patent: May 12, 2015Assignee: Lummus Technology Inc.Inventors: Ujjal K. Mukherjee, Mario C. Baldassari, Marvin I. Greene

Patent number: 6454932Abstract: 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.Type: GrantFiled: August 15, 2000Date of Patent: September 24, 2002Assignee: ABB Lummus Global Inc.Inventors: Mario C.
