Patent number: 12054761Abstract: Disclosed herein are methods, systems, and compositions for the pretreatment of biomass within seconds with low inhibitor formation. The pretreatment process is used to convert biomass to a fuel or other useful chemicals by subjecting the feedstock to a rapid retention time under pressure and temperature and/or chemical reactant. The system includes a continuously-operating valve discharge apparatus to discharge pretreated feedstock while maintaining uniform pressure on the pretreatment system.Type: GrantFiled: January 4, 2023Date of Patent: August 6, 2024Assignee: Apalta Patents OÜInventor: Robert E. Lumpkin

Patent number: 4146359Abstract: This invention relates to a new and novel method and apparatus for reacting nongaseous material with a gaseous reactant comprising introducing a first stream containing a nongaseous material into a reaction zone; simultaneously introducing a second stream containing a gaseous reactant into the reaction zone such that the gaseous reactant immediately contacts and reacts with the first stream thereby producing a gaseous product; forming a spiralling vortex within the reaction zone to cause substantial separation of gases, including the gaseous product, from the nongaseous material; forming and removing a third stream from the reaction zone containing the gaseous product which is substantially free of the nongaseous material before a major portion of the gaseous product can react with the nongaseous material; and forming and removing a fourth stream containing the nongaseous material from the reaction zone.Type: GrantFiled: June 25, 1976Date of Patent: March 27, 1979Assignee: Occidental Petroleum CorporationInventors: Robert E. Lumpkin, Kandaswamy Duraiswamy

Patent number: 4145274Abstract: In a continuous process for recovery of values contained in a solid carbonaceous material, the carbonaceous material is comminuted and then subjected to flash pyrolysis in the presence of a particulate heat source fed over an overflow weir to form a pyrolysis product stream containing a carbon containing solid residue and volatilized hydrocarbons. After the carbon containing solid residue is separated from the pyrolysis product stream, values are obtained by condensing volatilized hydrocarbons. The particulate source of heat is formed by oxidizing carbon in the solid residue.Type: GrantFiled: May 5, 1977Date of Patent: March 20, 1979Assignee: Occidental Petroleum CorporationInventors: Norman W. Green, Kandaswamy Duraiswamy, Robert E. Lumpkin, Bruce L. Winter

After the carbon containing solid residue is separated from the pyrolysis product stream, values are obtained by condensing volatilized hydrocarbons. The particulate source of heat is formed by oxidizing carbon in the solid residue and separating out the fines.Type: GrantFiled: June 25, 1976Date of Patent: July 25, 1978Assignee: Occidental Petroleum CorporationInventors: Norman W. Green, Kandaswamy Duraiswamy, Robert E. Lumpkin

Patent number: 4101263Abstract: Nongaseous carbonaceous material is heated by a method comprising introducing tangentially a first stream containing a nongaseous carbonaceous material and carbon monoxide into a reaction zone; simultaneously and separately introducing a second stream containing oxygen into the reaction zone such that the oxygen enters the reaction zone away from the wall thereof and reacts with the first stream thereby producing a gaseous product and heating the nongaseous carbonaceous material; forming an outer spiralling vortex within the reaction zone to cause substantial separation of gases, including the gaseous product, from the nongaseous carbonaceous material; removing a third stream from the reaction zone containing the gaseous product which is substantially free of the nongaseous carbonaceous material before a major portion of the gaseous product can react with the nongaseous carbonaceous material; and removing a fourth stream containing the nongaseous carbonaceous material from the reaction zone.Type: GrantFiled: June 25, 1976Date of Patent: July 18, 1978Assignee: Occidental Petroleum CorporationInventor: Robert E. Lumpkin, Jr.
