  • PROCESS FOR PRODUCING HIGH VALUE PRODUCTS FROM BIOMASS
    Publication number: 20140234934
    Abstract: A process for converting biomass into high value energy products is provided comprising the steps of: debarking, chipping, and screening wood; separating a plurality of hemicellulose from a plurality of cellulose and lignin; hydrolyzing the plurality of hemicellulose into monosaccharides; fermenting the monosaccharides using immobilized Pachysolen tannophilus; removing the lignin from the plurality of cellulose and lignin; and making a paper pulp from the plurality of cellulose.
    Type: Application

  • METHODS OF TREATING BIOMASS
    Publication number: 20120301939
    Abstract: A process for producing biofuel from biomass that includes free monosaccharides is provided. The process comprises the steps of mixing the biomass with a recycled hydrolysate for a sufficient time to elute a portion of the free monosaccharides from the biomass thereby forming a sugar enriched hydrolysate. Sugar enriched hydrolysate is then separated from the biomass and monosaccharides contained in the separated sugar enriched hydrolysate are fermented.
