METHOD FOR TREATING A LIGNOCELLULOSIC BIOMASS

The aim of the invention is a method 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) undertaking solid/liquid separation of the impregnated lignocellulosic substrate; f) pretreating said substrate originating from step e) by cooking; g) completing an enzymatic hydrolysis of the pretreated lignocellulosic substrate; h) fermenting the hydrolysat originating from step g); and - introducing the used aqueous washing solution into a step of said method for treating the biomass following the pretreating step f), and/or into a step of producing enzymes, and/or into a step of producing/propagating microorganisms that are needed in steps g) or h). 本发明的主题是处理木质纤维素生物质的方法，其包括以下步骤：a)调节木质纤维素生物质，b)洗涤所述颗粒，c)将经洗涤的生物质颗粒与水性溶液分离，d)采用酸性液体浸渍所述木质纤维素基质，e)对经浸渍的木质纤维素基质进行固/液分离，f)通过蒸煮对来自步骤e)的所述基质进行预处理，g)对经预处理
