    Abstract: The object is to produce a polysaccharide and/or a monosaccharide efficiently by hydrolyzing a different polysaccharide efficiently. The hydrolysis of a polysaccharide is an important means for producing a monosaccharide that can be used as a starting material for the production of ethanol, the solubilization of a water-insoluble polysaccharide, and the production of a useful water-soluble low-polymeric saccharide or the like. For achieving the object, a polysaccharide to be hydrolyzed is reacted with water in the presence of a carbonaceous material having sulfonic acid group therein to cause the hydrolysis of the polysaccharide to be hydrolyzed, thereby producing a other polysaccharide and/or a monosaccharide.

    Abstract: 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.

  • Publication number: 20090054863
    Abstract: A method for alteration of the morphology of cellulose fibers, particularly softwood fibers, by (a) subjecting the fibers to a metal ion-activated peroxide treatment carried out at a pH of between about I and about 9, preferably between 3 and 7, and (b) subjecting the treated fibers to a refining treatment thereby converts SW fibers to HW-like fibers in many respects. The metal ion-activated peroxide treatment has been noted to act on pulp cellulose and hemi-cellulose, causing oxidation and oxidative degradation of cellulose fibers. The chemical treatment of the pulp, taken alone, is not sufficient to attain the desired modification of the morphology of the fibers, however, subsequent refining or like mechanical treatment of the chemically-treated fibers to achieve a given degree of refinement of the fibers requires dramatically less refining energy to achieve a desired end point of refinement and to impart other desirable properties to the pulp.

  • Publication number: 20090054637
    Abstract: The present invention provides a thermoplastic resin film which has uniform optical properties and can be used for a high quality functional film and a method for producing the same to suppress uneven thickness in the machine direction of a film and streaks in the film. The method for producing a cellulose acylate film (12), includes the steps of melting a thermoplastic resin in a single screw extruder (22), discharging and feeding the molten resin to a die (24) through the extruder (22), extruding the molten resin from the die (24) in the form of a sheet, and solidifying the molten resin by cooling, wherein the extruder has a feed section (A), a compression section (B) and a metering section (C) and transport efficiency ?F of the thermoplastic resin in the feed section (A) is 0.2 to 0.7.
