资源简介：
Processes disclosed are capable of converting biomass into high-crystallinity， hydrophobic cellulose. In some variations， the process includes fractionating biomass with an acid (such as sulfur dioxide)， a solvent (such as ethanol)， and water， to generate cellulose-rich solids and a liquid containing hemicellulose and lignin; and depositing lignin onto cellulose fibers to produce lignin-coated cellulose materials (such as dissolving pulp). The crystallinity of the cellulose material may be 80% or higher， translating into good reinforcing properties for composites. 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 hydrophobic cellulose to form completely renewable composites.
