Abstract: Processes disclosed are capable of converting biomass into high-crystallinity nanocellulose with low mechanical energy input. In some variations, the process includes fractionating biomass with lignosulfonic acids, to generate cellulose-rich solids; and mechanically treating the cellulose-rich solids to form nanofibrils and/or nanocrystals. The strong lignosulfonic acids created during delignification give a pH less than 1 and hydrolyze preferentially the amorphous regions of cellulose. The total mechanical energy may be less than 500 kilowatt-hours per ton. The crystallinity of the nanocellulose material may be 80% or higher, translating into good reinforcing properties for composites. The nanocellulose material may include nanofibrillated cellulose, nanocrystalline cellulose, or both. In some embodiments, the nanocellulose material is hydrophobic via deposition of lignin onto the cellulose surface. Optionally, sugars derived from amorphous cellulose and hemicellulose may be separately fermented to co-products.

Abstract: In some variations, the invention provides a process for producing purified cellulose, comprising: providing a feedstock comprising lignocellulosic biomass; contacting the feedstock with sulfur dioxide, water, and a solvent for lignin, to produce intermediate solids and a liquid phase comprising hemicelluloses and lignin; mildly bleaching the intermediate solids to further delignify the intermediate solids, thereby generating cellulose-rich solids; and washing the cellulose-rich solids to generate purified cellulose with less than 2 weight percent lignin. The bleaching may employ bleaching agents including lignin-modifying enzymes. The bleaching and washing steps may be combined. It is also possible to carry out bleaching prior to, or simultaneously with, biomass fractionation in the digestor, which may help reduce downstream lignin precipitation. The purified cellulose may be utilized for making cellulose materials or cellulose derivatives, or for hydrolysis to produce glucose.

Abstract: The present invention generally provides methods of improving lignin separation during biomass fractionation with an acid to release sugars and a solvent for lignin (such as ethanol). In some embodiments, a digestor is employed to fractionating a feedstock in the presence of a solvent for lignin, sulfur dioxide, and water, to produce a liquor containing hemicellulose, cellulose-rich solids, and lignin. A solid additive is added to the digestor, wherein the solid additive combines with at least a portion of the lignin. Then a mixture of lignin and the solid additive is separated from the liquor, prior to hemicellulose recovery. Optionally, a solid additive may also be introduced to a hydrolysis reactor for converting hemicellulose oligomers to monomers, to improve separation of acid-catalyzed lignin. In some embodiments, the solid additive is gypsum or a gypsum/lignin mixture.

Abstract: A process for production of C5 and C6 sugar enriched syrups from lignocellulosic biomass and fermentation products therefrom is described. A lignocellulosic biomass is treated with acetic acid with washing thereof with a C 1 -C 2 acid-miscible organic solvent, (e.g., ethyl acetate). A soluble hemicellulose and lignin enriched fraction is obtained separately from a cellulose pulp enriched fraction and lignin is removed from the soluble hemicellulose fraction. The soluble hemicellulose and lignin enriched fraction is subjected to liquid / liquid separation to obtain an aqueous phase enriched in C5 sugars and C6 sugars and reduced in content of acetic acid. The syrup is suitable for fermentation. The process also produces fractions of organic-insoluble lignin, organic-soluble lignin, and acetate salts.
