    摘要: A process is provided for producing a lignin-coated cellulose material, comprising: pre-extracting a lignocellulosic biomass feedstock in the presence of steam or hot water, depositing lignin from the liquid onto a surface of solids to generate a lignin-coated intermediate material; optionally drying the intermediate material; digesting the lignin-coated intermediate material in the presence of an acid, a solvent for lignin, and water, wherein the rate of delignification of surface lignin is lower than the rate of delignification of bulk lignin; and recovering a hydrophobic lignin-coated cellulose material. In some variations, part of the overall process is a combination of Green Power+® and AVAP® technologies. A cellulose-rich composition is provided, containing about 5 wt% to about 15 wt% total lignin, with particles having a higher average surface concentration of lignin compared to an average bulk (internal) concentration of lignin.

    摘要: 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 sulfur dioxide or a sulfite compound and water, to generate cellulose-rich solids and a liquid containing hemicellulose and lignin; and mechanically treating the cellulose-rich solids to form nanofibrils and/or nanocrystals. 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 some lignin onto the cellulose surface. Optionally, sugars derived from amorphous cellulose and hemicellulose may be separately fermented, such as to monomers for various polymers. These polymers may be combined with the nanocellulose to form completely renewable composites.
