CA 2220335

The present invention relates to a continuous process for acid hydrolysis of lignocellulosic material through which the delignification and saccharification operations are carried out in a single reaction cycle utilizing a solubilizing organic solvent of lignin and a strong and extremely diluted inorganic acid, and obtaining highly concentrated recoveries of sugar. For the execution of the present process a hydrolysis reactor is further presented.

Procédé continu pour l'hydrolyse acide de matières lignocellulosiques, selon lequel les opérations de délignification et de saccharification s'effectuent au cours d'un seul cycle réactionnel à l'aide d'un solvant organique solubilisant de la lignine et d'un acide minéral fort et extrêmement dilué, et l'on récupère du sucre fortement concentré. On a également prévu un réacteur d'hydrolyse pour la mise en oeuvre de ce procédé.
