摘要： A method for utilizing biomass components, namely cellulose, hemicellose, and lignin, and converting them to value-added biobased chemical products is described herein. The present method provides treatments to obtain a plurality of component streams from biomass for producing derivative products while minimizing waste products.

摘要： An integrated process for the production of ethanol from woody plant material is provided, the process comprising: contacting a continuous flow of the plant material with a counter-current continuous flow of an aqueous ethanol solution at elevated temperature and pressure to provide plant material depleted of lignin; removing ethanol from the lignin-depleted plant material; contacting a continuous flow of the lignin-depleted plant material with water at elevated temperature and pressure to solubilize xylose within the plant material; and hydrolyzing cellulose present in the plant material to form glucose, which in turn is fermented to produce ethanol.

摘要： The present invention is directed generally to a method of production of biobased chemicals from lignin sources, including waste lignin. This method may allow for selectively producing biobased chemicals from lignin sources using certain processing methods. The methods for production of these biobased chemicals may be provided by oxidative processing in the presence of a caustic. Further, the oxidative processing, including catalytic oxidative processing and stoichiometric oxidative processing, may also be used. The present invention may also provide control over lignin bond fragmentation in the selective production of the biobased chemicals.
