PROCESS AND SYSTEM FOR HIGH SOLIDS FERMENTATION

摘要

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.
