Aqueous fractionation of biomass based on novel carbohydrate hydrolysis kinetics

Yes

The present invention is a continuation-in-part of U.S. patent application Ser. No. 08/723,399 filed Sep. 30, 1996, now U.S. Pat. No. 6,022,419, and relates to the innovation of introducing a process hot washing step at elevated temperatures (>135.degree. C.) before the hydrolysis liquors or the treated solids are flashed to atmospheric pressure in a continuous process of using hot acidic medium for hydrolysis and fractionation of biomass into its major components, in several stages.
