"METHOD FOR SEPARATING LIGNOCELLULOSE CONTAINING BIOMASS"

Abstract A method of separating lignocellulose-containing biomass, particularly of wood, linto its important components in the form lof lignin, hemicellulose and cellulose which includes the following steps: a) pre-hydrolysing the lignocellulose- containing biomass by treatment with water of stream; b) extracting the hydrolysed hemicellulose formed by prehydrolysis with an aqueous medium; c) extracting the process-modified lignin remaining in the residue with an alkanolamine, isolating the lignin, recovering the alkanolamine, whereby the alkanolamine is substituted by alkyl groups on the nitrogen, and d) producing a cellulose raw material.
