abstract process for fractioning lignocellulosic biomass the present invention is directed to a process for fractioning lignocellulosic biomass for the purpose of reducing process costs, increasing delignification, reducing side reactions, in particular reducing the degradation of hemicelluloses, improving hydrolysis cellulose and increasing the nativity of the obtained lignin, by performing the biomass fractionation organosolve with a treatment liquid at a temperature below 170 ° C, in which the treatment liquid comprises a non-hydroxyl organic solvent, in particular a ketone, water and some acid, and optionally subjecting the product stream enriched with cellulose to enzymatic hydrolysis. |
