Claim Text:
1. A process for the hydrolysis of a liquid biomass feed stream derived from pre-treated lingo-cellulosic biomass comprising cations in the form of inorganic salts and xyloligomers containing xylose, wherein the process comprises the steps of A. creating an acidic stream from the liquid biomass feed stream by decationization of the liquid biomass feed stream using an ion exchange media to increase the number of H B. separating at least a portion of the acidic stream from the ion exchange media, and C. hydrolyzing the at least a portion of the acidic stream in the absence of any ion exchange media by increasing the temperature of the acidic stream to a hydrolysis temperature in the range of between 150° C. and 200° C.
