  • Patent number: 8546116
    Abstract: A method and apparatus for fractionating a lignocellulose-based biomass are provided. The method includes providing a lignocellulose-based biomass, extracting lignin from the biomass by adding a first solvent capable of dissolving the lignin, extracting xylose by adding a second solvent capable of dissolving hemicellulose to the biomass treated with the first solvent, and extracting the cellulose remaining in the biomass. In this method, a continuous process can be performed instead of a low efficiency batch-type process and components of the biomass can be obtained at high yield.
