ABSTRACT:
Processes for treating cellulosic substances prior to hydrolysis which lead to shortening hydrolysis time and to increasing sugar yield. As exemplary, an aqueous slurry of the cellulosic substance is acidified and heated to and maintained at a temperature to produce a change in the cellulosic structure; the heating period is controlled so that there is little glucose formation. The pretreated cellulose may be subsequently hydrolyzed by acid or enzyme.
