Abstract
A process and system for producing ethanol from a biomass feedstock is provided that improves ethanol production by using a biomass feedstock containing high amounts of solids and starch. The process can involve subjecting the biomass feedstock to a primary fermentation to produce a whole stillage and subjecting this whole stillage to a secondary fermentation. The processes and systems described herein can maximize the amount of ethanol produced in ethanol production facilities.
Claims24
A method for producing a biomass-derived product, the method comprising:
- subjecting a primary whole stillage to fermentation to thereby produce a fermentation product comprising a secondary whole stillage and ethanol, wherein the whole stillage has a starch content of at least 15 weight percent on a dry matter basis.
