摘要： A process for treating cellulosic materials to obtain glucose therefrom, which process includes an initial acid or base treatment of the cellulosic materials to remove hemicellulose, followed by a solvent treatment of the solid residue to dissolve the native cellulose contained therein. The dissolved cellulose is separated from the solid lignin-containing residue, whereafter the cellulose is reprecipitated by contacting the solution thereof with water. The reprecipitated cellulose is hydrolyzed to glucose either by acid or enzyme hydrolysis. If desired, the cellulose may be reprecipitated and hydrolyzed in the presence of the lignin-containing solid, the latter being separated from the glucose.

摘要： The invention relates to the prehydrolysis of lignocellulose by passing an acidic or alkaline solution through solid lignocellulosic particles with removal of soluble components as they are formed. The technique permits a less severe combination of pH, temperature and time than conventional prehydrolysis. Furthermore, greater extraction of both hemicellulose and lignin occurs simultaneously in the same reactor and under the same conditions.
