SEPARATION OF PROTEINS FROM GRASSES INTEGRATED WITH AMMONIA FIBER EXPLOSION (AFEX) PRETREATMENT AND CELLULOSE HYDROLYSIS

摘要

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.
