    摘要： Provided is a method comprising (a) providing a hydrolysis composition of at least 20 wt % of sugar equivalents, wherein the hydrolysis composition comprises a first oligosaccharide, water, optionally a soluble aromatic compound, (b) contacting the hydrolysis composition with a catalyst in a first reactor to hydrolyze at least a portion of the first oligosaccharide to form a first product composition comprising a first monosaccharide and a second oligosaccharide, (c) separating the first monosaccharide from the first product composition to form a second product composition comprising the second oligosaccharide, wherein at least a portion of the second oligosaccharide is a reversion sugar, and (d) converting via a further hydrolysis step at least a portion of the second oligosaccharide to form a third product composition comprising a second monosaccharide.

    摘要： Disclosed are methods of functionalizing lignin using reactive extraction. The invention also generally relates to functionalized lignin. An exemplary method for producing functionalized lignin is disclosed, which comprises: providing a residue comprising lignin and cellulose; subjecting the residue to a liquid comprising an organic compound, thereby forming a first mixture; wherein the subjecting is performed at a first temperature of about 100° C. or less; and wherein the first mixture comprises: a first liquid fraction comprising solubilized functionalized lignin, wherein the solubilized functionalized lignin is functionalized with the organic compound; and a first solid fraction comprising cellulose.

    摘要： Methods are disclosed for the continuous treatment of biomass comprising a pretreatment step, wherein said biomass is contacted with a first supercritical, near-critical, or sub-critical fluid to form a solid matrix and a first liquid fraction; and a hydrolysis step, wherein said solid matrix formed in said pretreatment step is contacted with a second supercritical or near-supercritical fluid to produce a second liquid fraction and a insoluble lignin-containing fraction. Also disclosed are apparatuses for the continuous conversion of biomass comprising a pretreatment reactor and a hydrolysis reactor associated with said pretreatment reactor.
