Publication number: 20220372373Abstract: A combined hydrothermal liquefaction (HTL) and catalytic hydrothermal gasification (CHG) system and process are described that convert various biomass-containing sources into separable bio-oils and aqueous effluents that contain residual organics. Bio-oils may be converted to useful bio-based fuels and other chemical feedstocks. Residual organics in HTL aqueous effluents may be gasified and converted into medium-BTU product gases and directly used for process heating or to provide energy.Type: ApplicationFiled: July 27, 2022Publication date: November 24, 2022Applicant: Battelle Memorial InstituteInventors: Douglas C. Elliott, Gary G. Neuenschwander, Todd R. Hart

Patent number: 9404063Abstract: A system and process are described for clean separation of biocrudes and water by-products from hydrothermal liquefaction (HTL) product mixtures of organic and biomass-containing feedstocks at elevated temperatures and pressures. Inorganic compound solids are removed prior to separation of biocrude and water by-product fractions to minimize formation of emulsions that impede separation. Separation may be performed at higher temperatures that reduce heat loss and need to cool product mixtures to ambient. The present invention thus achieves separation efficiencies not achieved in conventional HTL processing.Type: GrantFiled: November 5, 2014Date of Patent: August 2, 2016Assignees: Battelle Memorial Institute, Genifuel CorporationInventors: Douglas C. Elliott, Todd R. Hart, Gary G. Neuenschwander, James R. Oyler, Leslie J. Rotness, Jr., Andrew J. Schmidt, Alan H. Zacher

Patent number: 8241605Abstract: Continuous processing of wet biomass feedstock by catalytic hydrothermal gasification must address catalyst fouling and poisoning. One solution can involve heating the wet biomass with a heating unit to a temperature sufficient for organic constituents in the feedstock to decompose, for precipitates of inorganic wastes to form, for preheating the wet feedstock in preparation for subsequent separation of sulfur contaminants, or combinations thereof. Treatment further includes separating the precipitates out of the wet feedstock, removing sulfur contaminants, or both using a solids separation unit and a sulfur separation unit, respectively. Having removed much of the inorganic wastes and the sulfur that can cause poisoning and fouling, the wet biomass feedstock can be exposed to the heterogeneous catalyst for gasification.Type: GrantFiled: December 19, 2008Date of Patent: August 14, 2012Assignee: Battelle Memorial InstituteInventors: Douglas C. Elliott, Robert Scott Butner, Gary G. Neuenschwander, Alan H. Zacher, Todd R. Hart

Patent number: 7652131Abstract: The invention includes methods of processing plant material by adding water to form a mixture, heating the mixture, and separating a liquid component from a solid-comprising component. At least one of the liquid component and the solid-comprising component undergoes additional processing. Processing of the solid-comprising component produces oils, and processing of the liquid component produces one or more of glycerol, ethylene glycol, lactic acid and propylene glycol. The invention includes a process of forming glycerol, ethylene glycol, lactic acid and propylene glycol from plant matter by adding water, heating and filtering the plant matter. The filtrate containing starch, starch fragments, hemicellulose and fragments of hemicellulose is treated to form linear poly-alcohols which are then cleaved to produce one or more of glycerol, ethylene glycol, lactic acid and propylene glycol. The invention also includes a method of producing free and/or complexed sterols and stanols from plant material.Type: GrantFiled: November 3, 2004Date of Patent: January 26, 2010Assignee: Battelle Memorial InstituteInventors: Todd A.
