20140134745 | METHOD FOR EVALUATION OF LIGNIN - According to one aspect of the present method, a method for evaluation of lignin may comprise the steps of: providing lignin from a source, wherein the composition of lignin is unknown; analyzing the lignin by molecular spectroscopy methods and/or physical-chemical analysis; determining the composition of the lignin; and using the determination of the composition to predict at least one biobased product produced from the lignin. Within the method, a statistical analysis of the lignin may provide a prediction for one or more products produced and/or the yield of one or more products. | 05-15-2014 |
20130012610 | LIGNIN AND OTHER PRODUCTS ISOLATED FROM PLANT MATERIAL, METHODS FOR ISOLATION AND USE, AND COMPOSITIONS CONTAINING LIGNIN AND OTHER PLANT-DERIVED PRODUCTS - 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. | 01-10-2013 |
20130005952 | RECOVERY OF LIGNIN AND WATER SOLUBLE SUGARS FROM PLANT MATERIALS - 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. | 01-03-2013 |
