  • Methods for furfural production from branched non-fermentable sugars in stillage or syrup
    Patent number: 9024047
    Abstract: 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.

  • Production of high solids syrup from lignocellulosic biomass hydrolysate fermentation broth
    Patent number: 8721794
    Abstract: Lignocellulosic biomass hydrolysate fermentation broth may be processed to produce a high solids syrup having relatively low viscosity that has a high energy content and may be burned in a fermentation production process. The high solids syrup was achieved through liquid/solid separation of broth or depleted broth producing a thin stillage with low suspended solids allowing evaporation to high solids while maintaining low viscosity.
