NOVELTY - A lignocellulosic biomass containing a primary solid fraction having insoluble lignin and a primary liquid fraction having soluble 6C saccharide and optionally soluble lignin is maintained at primary pressure and temperature. The primary temperature and pressure are reduced at specific condition, and mixture containing secondary solid fraction having insoluble lignin and precipitated lignin, and a secondary liquid fraction comprising saccharide is formed. Thus, lignin is produced from lignocellulosic biomass.    USE - Manufacture of lignin used as fuel, tackifier, phenol formaldehyde resin extender in manufacture of particle board and plywood, manufacture of molding compounds, urethane and epoxy resin, antioxidant, controlled-release agent, flow control agent, cement/concrete mixing, plasterboard production, oil drilling, dispersing agent, tanning leather, road covering, vanillin production, dimethyl sulfide and dimethyl sulfoxide production, phenol substitute, aromatic (phenol) monomer, additional miscellaneous monomer, carbon fiber, metal sequestration in solution, basis of gel formation and polyurethane copolymer (all claimed).    ADVANTAGE - Lignin is efficiently manufactured with improved energy recovery and without fouling the equipment.    DETAILED DESCRIPTION - A lignocellulosic biomass containing a primary solid fraction having insoluble lignin and a primary liquid fraction having soluble 6C saccharide and optionally soluble lignin is maintained at primary pressure and temperature. The primary temperature is reduced to secondary temperature, which is 1 degrees C more than the glass transition temperature of lignin under primary pressure. The primary pressure is reduced to secondary pressure in time of less than 1 second to precipitate soluble lignin, and mixture containing secondary solid fraction having insoluble lignin and precipitated lignin, and a secondary liquid fraction comprising soluble 6C saccharide is formed. Thus, lignin is produced from lignocellulosic biomass. An INDEPENDENT CLAIM is included for composition comprising lignin processed from lignocellulosic biomass using supercritical or near critical fluid extraction.
