Abstract: This invention provides a process for producing biomass pellets and fermentable sugars from cellulosic biomass, comprising: extracting cellulosic biomass feedstock with steam and/or hot water to produce an extract liquor containing hemicellulosic oligomers, dissolved lignin, and cellulose-rich solids, wherein at least some of the steam and/or hot water is derived from an internal or external source of fermentation vinasse; separating at least a portion of the hemicellulosic oligomers from the cellulose-rich solids, to produce intermediate solids; hydrotorrefying the intermediate solids to produce the energy-dense biomass, wherein water for hydrotorrefaction is derived, at least in part, from the internal or external source of fermentation vinasse; pelletizing the energy-dense biomass to form biomass pellets; and hydrolyzing the hemicellulosic oligomers into fermentable sugars. The fermentation vinasse may be recycled from downstream operations involving fermentation of the sugars. Or the fermentation vinasse may be obtained from a first-generation ethanol plant, for example.

Abstract: This invention provides processes to convert biomass, including wood and agricultural residues, to levulinic acid and co-products. Some variations treat feedstock with steam and/or hot water to produce an extract liquor containing hemicellulosic oligomers, lignin, and cellulose-rich solids, wherein the hemicellulosic oligomers comprise C5 hemicelluloses and C6 hemicelluloses; separate the cellulose-rich solids from the extract liquor, to produce dewatered solids containing cellulose and lignin; dehydrate the hemicellulosic oligomers to convert the C6 hemicelluloses directly to 5-hydroxymethylfurfural; and convert the 5-hydroxymethylfurfural to levulinic acid. Also, the cellulose may be dehydrated directly to 5-hydroxymethylfurfural, which may then be converted to additional levulinic acid. Various biorefinery embodiments are disclosed, in which C5 and C6 sugars are processed separately or in combination.

Abstract: The invention provides processes for producing fermentable sugars from whole biomass that includes cellulose, hemicellulose, lignin, and non-lignocellulosic sugars. Some variations fractionate the whole feedstock in the presence of sulfur dioxide, a solvent for lignin, and water, to produce a liquor containing hemicellulose, cellulose-rich solids, lignin, and the non-lignocellulosic sugars. After removing the cellulose-rich solids from the liquor, the hemicellulose is hydrolyzed to hemicellulosic monomers; the cellulose-rich solids are hydrolyzed to glucose; and the hemicellulosic monomers, the glucose, and the non-lignocellulosic sugars are all recovered (separately or in combination) as fermentable sugars. The whole biomass feedstock may be selected from sugarcane, energy cane, corn, wheat, rice, sugar beets, energy beets, etc. Typical non-lignocellulosic sugars are sucrose or starch, which may be converted to monomer sugars during initial fractionation. The invention provides a convenient biorefining system, avoiding expensive logistics associated with separating agricultural residues at harvest or following transportation.
