METHODS FOR CONDITIONING PRETREATED BIOMASS

摘要

Methods for producing ethanol from cellulosic biomass and, in particular, methods for conditioning pretreated biomass are disclosed. In some embodiments, pretreated biomass is contacted with a cooling fluid in a flash vessel to cool the biomass. The amount of alkaline solution contacted with the biomass may be based on the pH of partially hydrolyzed pretreated biomass in a liquefaction bioreactor.
