20090252922 | ANTIMICROBIAL FLUOROPOLYMER FILM, LAMINATES AND ARTICLES AND PROCESS FOR MAKING THEREOF - Films, laminates and articles comprising a fluoropolymer that contains amino-reactive functional groups only after activation are made antimicrobial by activating the fluoropolymer surface and then contacting the activated surface with a solution comprising chitosan. Films, laminates and articles comprising activated fluoropolymers and contacted with a solution comprising chitosan. | 10-08-2009 |
20090292115 | PROCESSES FOR CHEMICAL SYNTHESIS OF LIPOCHITOOLIGOSACCHARIDES - Processes for the synthesis of lipochitooligosaccharides were developed. A fully acylated oligoglucosamine precursor is prepared and reacted with a glucosamine monomer that has an amine protecting phthaloyl group. With removal of the phthaloyl group, a fatty acid may be added on the terminal glucosamine unit, forming a lipochitooligosaccharide. The processes can be adapted for use on a commercial scale. | 11-26-2009 |
20100124770 | PROCESS FOR PRODUCING A CONCENTRATED SUGAR SOLUTION BY ENZYMATIC SACCHARIFICATION OF POLYSACCHARIDE ENRICHED BIOMASS - Methods for obtaining concentrated sugar solution from polysaccharide enriched biomass by contacting biomass with water and at least one nucleophilic base to produce a polysaccharide enriched biomass comprising a solid fraction and a liquid fraction and then contacting the solid fraction with saccharification enzyme consortium to produce a saccharification product comprising at least about 7 percent by weight sugars in 24 hours. The methods include optionally adding at least one additive selected from the group consisting of polyethylene glycols, fatty acid esters, fatty acid ethoxylates, nonionic surfactants derived from polyethoxylated sorbitan and a fatty acid, sodium lauriminodipropionate, sodium cocoamphoacetate, sodium tridecyl ether sulfate and a combination of these, such that enzyme loading of the saccharification enzyme consortium can be reduced. | 05-20-2010 |
20100124771 | DELIGNIFICATION OF BIOMASS WITH SEQUENTIAL BASE TREATMENT - A method for the production of a saccharification product is provided, the method comprising:

20100124772 | PROCESS FOR PRODUCING A SUGAR SOLUTION BY COMBINED CHEMICAL AND ENZYMATIC SACCHARIFICATION OF POLYSACCHARIDE ENRICHED BIOMASS - Concentrated sugar solutions obtained from polysaccharide enriched biomass by contacting biomass with water and at least one nucleophilic base to produce a polysaccharide enriched biomass comprising a solid fraction and a liquid fraction and then contacting enriched biomass with a dilute mineral acid selected from the group consisting of sulfuric acid, phosphoric acid, hydrochloric acid, nitric acid, or a combination thereof, to produce an intermediate saccharification product, which is contacted with an enzyme consortium to produce a final saccharification product comprising fermentable sugars. | 05-20-2010 |
20100125135 | SUGAR PRODUCTION BY DECRYSTALLIZATION AND HYDROLYSIS OF POLYSACCHARIDE ENRICHED BIOMASS - Sugar solutions are obtained from polysaccharide enriched biomass by contacting biomass with water and at least one nucleophilic base to produce a polysaccharide enriched biomass comprising a solid fraction and a liquid fraction. The solid fraction is separated from the lignin-containing liquid fraction and contacted with an acid solution, the acid solution comprising about 70 weight percent to about 100 weight percent sulfuric acid or an acid mixture comprising phosphoric acid and sulfuric acid, at a temperature and for a reaction time sufficient to produce a decrystallized biomass mixture. Water is added and the diluted biomass mixture is then hydrolyzed to produce a saccharification product comprising sugars. | 05-20-2010 |
20100242729 | STORAGE MATERIALS FOR HYDROGEN AND OTHER SMALL MOLECULES - This invention relates to adsorbents useful for storing hydrogen and other small molecules, and to methods for preparing such adsorbents. The adsorbents are produced by heating carbonaceous materials to a temperature of at least 900° C. in an atmosphere of hydrogen. | 09-30-2010 |
20120157697 | PROCESS FOR FURFURAL PRODUCTION FROM BIOMASS - Furfural is produced from a lignocellulosic feedstock comprising glucan and xylan. The feedstock is contacted with water in the presence of an acid catalyst. The resulting mixture is contacted with at least one water-immiscible organic solvent to form a mixture comprising an aqueous phase and an organic phase. Under suitable reaction conditions, furfural is produced and preferentially partitions into the organic phase, from which it may be recovered. | 06-21-2012 |
20130109869 | PRODUCTION OF FURFURAL FROM BIOMASS | 05-02-2013 |
20140051873 | METHODS FOR FURFURAL PRODUCTION FROM BRANCHED NON-FERMENTABLE SUGARS IN STILLAGE OR SYRUP - Furfural is obtained selectively and in good purity from non-fermentable branched sugars found in soluble waste streams of lignocellulosic biomass. In a monophasic method, stillage or syrup is contacted with water and an acid catalyst under suitable reaction conditions to convert the branched non-fermentable branched sugars to furfural. Additionally, the stillage or syrup can be treated with a water-immiscible organic solvent to form a biphasic mixture comprising an aqueous phase and an organic phase. The furfural that is produced preferentially partitions into the organic phase, from which it may be recovered. | 02-20-2014 |
