Patent number: 8759050Abstract: A process of producing ethanol from whole stillage, includes obtaining a supply of whole stillage from an ethanol production facility after ethanol has been extracted therefrom; pre-treating the whole stillage to convert hemicellulose portions of the whole stillage into sugars; adding enzymes to the whole stillage to convert cellulose portions of the whole stillage to sugars; fermenting the whole stillage to create a beer mixture; and distilling the beer mixture to separate ethanol therefrom. The pre-treating step may include adding acid to the whole stillage to decrease its pH level; heating and pressurizing the whole stillage; holding the whole stillage under pressure and heat for a dwell time; removing pressure from the whole stillage to cause flashing; and cooling the whole stillage before the enzymes are added.Type: GrantFiled: September 21, 2011Date of Patent: June 24, 2014Assignee: Quad County Corn ProcessorsInventor: Travis Brotherson

Publication number: 20130149750Abstract: A method for pretreating cellulose for fermentation in an aqueous environment comprises the steps of: grinding a biomass to reduce its particle size, adding water to the ground biomass to create a slurry, soaking the slurry, heating the slurry at a first pressure greater than atmospheric pressure, reducing the pressure of the slurry, reducing the temperature of the slurry, determining whether the enzymes used require preliminary enzymatic hydrolysis, and performing preliminary enzymatic hydrolysis on the slurry if the enzymes used require preliminary enzymatic hydrolysis.Type: ApplicationFiled: December 5, 2012Publication date: June 13, 2013Applicant: Quad County Corn ProcessorsInventor: Quad County Corn Processors
