Title: Methods of recovering lignin and other products from biomass

Abstract

Methods of recovering lignin products and other products from biomass. The method comprises adding a chemical agent to a stored biomass comprising lignin to form a chemically-treated biomass. The chemical agent comprises an acid, a base, an inorganic salt, or a combination of the inorganic salt and one of the acid or the base. The chemically-treated biomass is stored under anaerobic conditions. Lignin products, such as high molecular weight lignin, medium molecular weight lignin, or low molecular weight lignin, are recovered from the chemically-treated biomass. Additional methods of recovering lignin products and other products from biomass are disclosed.

Method for selectively preparing evoglucosenone (LGO) and other anhydrosugars from biomass in polar aprotic solvents

Patent Huber, George W.; Cao, Fei; Dumesic, James A.; ...

A method to produce 5-hydroxymethylfurfural (HMF) is described in which a reactant including cellulose, lignocellulose, or a combination thereof, in a reaction mixture of a polar, aprotic solvent and an acid is reacted for a time, at a temperature, and at a hydrogen ion concentration wherein at least a portion of the cellulose or lignocellulose present in the reactant is converted to HMF. The reaction mixture is initially substantially devoid of water. As the reaction proceeds, dehydration of intermediates causes the water concentration in the reaction mixture to rise to no more than about 2.0 wt % water.
