Separation of Proteins from Grasses Integrated with Ammonia Fiber Explosion (AFEX) Pretreatment and Cellulose Hydrolysis

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
A process for extracting an aqueous ammonium hydroxide solution from a plant biomass after an Ammonia Fiber Explosion (AFEX) process step, is described. The proteins can be separated before or after a hydrolysis of sugar precursors (carbohydrates) from the biomass to produce sugars for fermentation to produce ethanol. The proteins are useful as animal feeds because of their amino acid food values.
