  • Process for fractionating lignocellulosics
    Patent number: 10077283
    Abstract: A method for the isolation of lignin from a lignocellulosic biomass, comprising providing a lignocellulosic biomass; extracting sugar free lignin from the lignocellulosic biomass by contacting said biomass with an organic aqueous solution comprising water and at least one water miscible organic solvent, either discontinuously or continuously, whereby a biomass-solvent suspension is formed; separating the sugar free lignin solution from the biomass-solvent suspension to obtain a sugar free lignin solution and a cellulosic material enriched with lignin carbohydrate complexes and hemicellulose, and optionally isolating sugar free lignin from the sugar free lignin solution; extracting the lignin carbohydrate complexes from the cellulosic material enriched with lignin carbohydrate complexes and hemicellulose by contacting said cellulosic material with a liquid comprising at least water, whereby treated biomass suspension is formed; separating the lignin carbohydrate complexes solution from said treated biomass sus
