Patent number: 8888876Abstract: The present invention relates to a system and process for gasifying feedstock such as carbonaceous materials. The invention includes partial combustion of dry solids and pyrolysis of carbonaceous material slurry in two separate reactor sections and produce mixture products comprising synthesis gas. The invention employs one or more catalytic or sorbent bed for removing tar from the synthesis gas. The inventive system and process allow a gasification to be carried out under higher slurry feeding rate and lower temperature with the provision to manage the tar being produced, therefore to increase the conversion efficiency of the overall gasification.Type: GrantFiled: May 8, 2013Date of Patent: November 18, 2014Assignee: Lummus Technology Inc.Inventors: Albert C. Tsang, Chancelor L. Williams, Max W. Thompson, David L. Breton

Patent number: 8444724Abstract: A generally upright reactor system for gasifying a feedstock. The reactor system generally includes a main body, at least two inlet projections extending outwardly from the main body, and at least one inlet positioned on each of the inlet projections. Each of the inlets is operable to discharge the feedstock into the reaction zone.Type: GrantFiled: May 31, 2012Date of Patent: May 21, 2013Assignee: Phillips 66 CompanyInventors: Steven L. Douglas, Ronald W. Herbanek, David L. Breton, Steven E. Chichester

Publication number: 20120294775Abstract: A novel tar-free gasification process and system is disclosed that involves the partial combustion of recycled dry solids and the drying of a slurry feedstock comprising carbonaceous material in two separate reactor zones in a two stage gasifier, thereby producing mixture products comprising synthesis gas. The synthesis gas produced from the high temperature first stage reaction zone is then quenched in the second stage reaction zone of the gasifier prior to introduction of a slurry feedstock. The temperature of the final syngas exiting the second stage reaction zone of the gasifier is thereby moderated to be in the range of about 350-900° F., which is below the temperature range at which tar is readily formed, depending upon the type of carbonaceous feedstock utilized.Type: ApplicationFiled: August 1, 2012Publication date: November 22, 2012Applicant: PHILLIPS 66 COMPANYInventors: Albert C. Tsang, David L. Breton

Patent number: 8088188Abstract: A system and process for gasifying carbonaceous feedstock with staged slurry addition in order to prevent the formation of tar that causes deposition problems. Dry solid carbonaceous material is partially combusted, then pyrolyzed along with a first slurry stream comprising carbonaceous material in two separate reactor sections, thereby producing mixture products comprising synthesis gas. The second slurry stream comprising particulate carbonaceous material is fed to a drying unit downstream of a heat recovery zone along with the mixture product exiting the heat recovery zone The resulting final temperature of the second stage mixture products and dried particulate carbonaceous material is between 450° F. and 550° F., a temperature range that is typically not conducive to the emission of heavy molecular-weight tar species.Type: GrantFiled: April 1, 2011Date of Patent: January 3, 2012Assignee: ConocoPhillips CompanyInventors: David L. Breton, Albert C. Tsang, Max W. Thompson
