Summary: | The present invention relates to a method for obtaining sugar and lignin fractions from lignocellulosic materials and to a method for producing fermentation products using the sugars obtained from the lignocellulose. In particular, the present invention relates to a method for improving the sugar yield in the enzymatic hydrolysate by introducing a pre-treatment step of hydrothermal hydrolysis and an alkaline delignification step.
La présente invention concerne un procédé d'obtention de fractions sucre et lignine à partir de matières lignocellulosiques et un procédé de production de produits de fermentation au moyen des sucres obtenus à partir de la lignocellulose. En particulier, la présente invention concerne un procédé d'amélioration du rendement en sucres dans l'hydrolysat enzymatique par l'introduction d'une étape de pré-traitement d'hydrolyse hydrothermique et d'une étape de délignification alcaline. |
