摘要： Methods of depolymerizing lignin and products obtained therefrom. The methods include reacting lignin in a liquid solvent comprising an oxidation catalyst with the solvent being in contact with 02 gas. The solvent can include aprotic polar solvents. The oxidation catalyst can include heterogeneous catalysts. The methods can be used in the oxidative catalytic fractionation of raw biomass to generate soluble aromatic monomers and a solid carbohydrate residue. Depolymerized lignin products include phenolic and benzoquinone monomers, such as p-hydroxybenzoic acid, vanillin, syringaldehyde, vanillic acid, and/or syringic acid.

摘要： A novel approach for the conversion of biomass based hemicellulose prehydrolysate to high value succinic acid has been investigated using a heterogeneous acid catalyst, Amberlyst 15 and hydrogen peroxide. A vital intermediate in this process, furfural, was oxidized in a biphasic system to produce succinic acid. Production of furfural in good yields is a limiting step in such processes for a number of reasons. Among the organic solvents evaluated, toluene was found to be an ideal solvent for furfural extraction and facilitated the conversion of furfural to succinic acid. Simultaneous extraction of furfural into the organic solvent as it is produced, increased the overall yield. It was observed that the developed method resulted in a succinic acid yield of 49% from the furfural obtained from hemicellulose prehydrolysate. It was found that 50 mg of Amberlyst 15 per mmole of furfural resulted in 100% FA conversion in less time.

摘要： A method of converting lignin to phenolic compounds and dicarboxylates in high yield is described. The method involves the use of peroxy acids to react with lignin at a moderated treatment conditions. The peroxy acids can be used along or in combination of other catalysts that have the capability to lower the molecular weight of lignin. A phenolic compounds yield is achieved (>60%) and these phenolic compounds represents high value precursors for various applications include but not limited to antioxidants, health improvement agents, anticorrosive agents, liquid fuel components and performance enhancing agents, resin and adhesives. Dicarboxylic acids can be used for polymer applications or hydrodeoxygenation to hydrocarbon fuel.
