Abstract
The subject of the invention is a process for treating lignocellulosic biomass comprising the following steps:
- a) conditioning the lignocellulosic biomass,b) washing said particles,c) separating the aqueous solution from the washed biomass particles,d) impregnating said lignocellulosic substrate with an acid liquor,e) carrying out a solid/liquid separation of the impregnated lignocellulosic substrate,f) pretreating said substrate from step e) by cooking,g) carrying out an enzymatic hydrolysis of the pretreated lignocellulosic substrate,h) carrying out a fermentation of the hydrolyzate from step g), and introducing the used aqueous washing solution into a step of said biomass treatment process which is after the pretreatment step f), and/or into an enzyme production step and/or into a step of producing/propagating the microorganisms necessary for steps g) or h).
