METHOD AND APPARATUS FOR FRACTIONATING LIGNOCELLULOSE-BASED BIOMASS

摘要

PURPOSE: A sorting method of lignocellulose-based biomass and a sorting device thereof are provided to improve processing efficiency through a continuous process, and to prevent excessive decomposition of xylose by successively extracting lignin and xylose. CONSTITUTION: A sorting method of lignocellulose-based biomass includes the following steps: offering lignocellulose-based biomass(S1); extracting lignin from biomass by adding a first solvent dissolving the lignin(S2); extracting xylose by adding a second solvent dissolving hemicelluloses(S3); and extracting the remaining cellulose from the extracted biomass. A sorting device includes a reaction vessel dipping the biomass, a second solvent tank, a first solvent tank, a first reservoir storing the lignin, and a reservoir including a second reservoir.
