    摘要: Non-food plant biomass is subjected hot-water extraction in a pressurized vessel at an elevated temperature up to about 250° C. without addition of reagents, to yield an aqueous extract containing hemicellulosic components and a lignocellulosic residue. The process leaves the lignocellulose substantially intact, but with the hemicellulosic content largely removed. The separated aqueous extract or liquor is concentrated and purified, and long-chain sugars are reduced into monomer saccharides. The lignocellulosic residue may be further processed, to yield a useful fibrous material that is highly resistant to sorption of water. This material may be used for composite materials that resist water degradation, or may be used to produce a higher thermal-yield, water-resistant fuel, or may be used as bioconversion feedstock for producing high-value, lignocellulosic derivatives.
