Process And System For Producing Ethanol From A Byproduct Of An Ethanol Production Facility
US Patent:
2012020, Aug 16, 2012
Filed:
Feb 14, 2011
Appl. No.:
13/026613
Inventors:
Travis Brotherson - Holstein IA, US
Assignee:
Quad County Corn Processors - Galva IA
International Classification:
C12P 7/10
US Classification:
435165
Abstract:
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.

Method For Pretreatment Of Cellulose For Fermentation In An Aqueous Environment
US Patent:
2013014, Jun 13, 2013
Filed:
Dec 5, 2012
Appl. No.:
13/706028
Inventors:

Travis Brotherson - Holstein IA, US
Assignee:
Quad County Corn Processors - Galva IA
International Classification:
C12P 19/14
US Classification:
435 99
Abstract:
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.
