Patent number: 10844413Abstract: 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: December 16, 2015Date of Patent: November 24, 2020Assignee: Sweetwater Energy, Inc.Inventor: Robert E.

Patent number: 8529765Abstract: A method, apparatus and system for the hydrolyzation of ensiled biomass is disclosed. Ensiled biomass is processed in multiple phases, resulting in a liquid precursor hydrozate and a solid precursor hydrozate. The liquid precursor having significant economic value, and being suitable for uses such as, for example, lower cost and improved efficiency ethanol production. A method for lower cost, improved efficiency alcohol production that uses the resulting liquid precursor hydrozate being produced at distributed sources is further disclosed.Type: GrantFiled: December 8, 2009Date of Patent: September 10, 2013Assignee: Sweetwater Energy, Inc.Inventor: Jerry Wayne Horton

Patent number: 8426161Abstract: A method for producing ethanol comprising the steps of providing feedstock, processing the feedstock at a feedstock processing plant adapted to produce sugar water and wet animal feed, separating the sugar water and wet animal feed, transporting the sugar water from the feedstock processing plant to an ethanol producing plant, and producing ethanol from the sugar water. A system for producing ethanol comprising a feedstock provider adapted to provide feedstock, feedstock, a feedstock processing plant adapted to produce sugar water and wet animal feed from the feedstock, a means for transporting the sugar water, and an ethanol producing plant adapted to produce ethanol from the sugar water.Type: GrantFiled: October 5, 2012Date of Patent: April 23, 2013Assignee: Sweetwater Energy, Inc.Inventor: Jerry W.

Patent number: 8323923Abstract: A method for producing ethanol is disclosed that uses a distributed production method where processing and pretreatment of combined liquid and solid material takes place outside of a centralized ethanol producing plant at a distributed feedstock processing plant, and separation of the resulting liquid and solid occurs prior to fermentation using this distributed production method. The resulting process liquid is then transported from each distributed feedstock processing plant to a centralized ethanol producing plant for fermentation, distillation and related processing. This novel distributed process reduces transportation costs, operating costs of ethanol producing plants, increases ethanol production throughput and improves the overall economics of ethanol production.Type: GrantFiled: October 11, 2007Date of Patent: December 4, 2012Assignee: Sweetwater Energy, Inc.Inventor: Jerry W.
