The present invention is directed to a process of producing ethanol from lignocellulosic biomass, which comprises pre-treating a lignocellulosic feedstock to produce a reactive carbohydrate mixture; adding activated carbon in free form; converting said reactive carbohydrate mixture to form a beer; separating solids from said carbohydrate mixture or said beer or both, wherein said activated carbon is separated along with the solids in said mixture, said beer or both; and drying said solids. The invention is also directed to the production of a dried solid fuel to be combusted during said process.
La présente invention porte sur un procédé de fabrication d'éthanol à partir de biomasse lignocellulosique. Ce procédé comprend les opérations consistant à prétraiter une charge d'alimentation lignocellulosique pour produire un mélange de glucides réactifs; ajouter du charbon actif sous forme libre; convertir ledit mélange de glucides réactifs pour former une bière; séparer les matières solides à partir dudit mélange de glucides ou de ladite bière ou des deux, ledit charbon actif étant séparé conjointement avec les matières solides dans ledit mélange, ladite bière ou les deux; et sécher lesdites matières solides. L'invention porte également sur la production d'un combustible solide séché devant être soumis à une combustion pendant ledit procédé.
