摘要： In one aspect, a process for treating woody plant material is provided, the process involving contacting the plant material with a continuous flow of an aqueous ethanol solution at elevated temperature and pressure under conditions that promote extraction of ethanol-soluble lignin from the plant material and retention of hemicellulose sugars, xylose and cellulose in the treated plant material solids. In another aspect, a process for extracting hemicellulose sugars from lignin-depleted plant material solids is provided, the process involving contacting lignin-depleted plant material with water at elevated temperature and pressure under conditions that promote extraction of hemicellulose sugars from the plant material; and recovering hemicellulose sugars from the liquid mixture.

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： Lignin polymers having distinctive properties, including a generally high molecular weight and generally homogeneous size distribution, as well as preservation of native reactive side groups, are isolated by solvent extraction of plant materials. Methods for isolation of lignin polymers, and for use of the isolated lignin polymers are disclosed. Compositions containing lignin isolated from plant materials, such as carbon fiber composites, resins, adhesive binders and coatings, polyurethane-based foams, rubbers and elastomers, plastics, films, paints, nutritional supplements, food and beverage additives are disclosed. Xylose and xylose derivatives, furfural, fermentable sugars, cellulose and hemi-cellulose products may be used directly or further processed. The lignin polymers and other plant-derived products disclosed herein may be produced in abundance at low cost, and may be used as substitutes for feedstocks originating from fossil fuel or petrochemical sources in the manufacture of various products.
