A method for treating lignocellulosic feedstock to produce a sugar rich process stream is disclosed. More specifically, lignocellulosic feedstock comprising cellulose, hemicellulose and lignin is subjected to disc refining followed by enzymatic hydrolysis performed under vacuum to produce said sugar rich process stream.The sugar nch process stream may subsequently be subjected to fermentation to produce biofuels such as ethanol and other chemicals.
L'invention porte sur un procédé de traitement de matières premières lignocellulosiques pour produire un liquide à traiter riche en sucre. Plus précisément, des matières premières lignocellulosiques comprenant de la cellulose, de l'hémicellulose et de la lignine sont soumises à un raffinage sur disques suivi d'une hydrolyse enzymatique réalisée sous vide pour produire ledit liquide à traiter riche en sucre, lequel peut ensuite être soumis à une fermentation pour produire des biocarburants tels que l'éthanol et autres produits chimiques.
