More Information
Summary:The invention concerns a continuous method for treating a lignocellulosic biomass before enzymatic hydrolysis, said method comprising a transfer of crushed then pressed biomass to a step of impregnation by an acid liquor, the impregnated biomass dripping over the area containing the impregnation liquor, then the resulting wet biomass is pressed and sent to a steam explosion step. The impregnation liquor is prepared in a dedicated area from the used liquor from the dripping operation and/or that from the pressing operation, prior to the explosion step. The invention also concerns the facility for implementing the method. (Figure 3)
