Claim Text:
1. A process for refining a sucrose-containing feedstock, said process comprising: (a) providing a feedstock containing lignocellulosic material and sucrose; (b) mechanically treating said feedstock to generate a sucrose-rich stream and sucrose-depleted lignocellulosic material, wherein said sucrose-depleted lignocellulosic material retains at least 1% of the initial sucrose contained in said feedstock; (c) extracting said sucrose-depleted lignocellulosic material with steam and/or hot water to produce cellulose-rich solids and an extract liquor containing hemicellulosic oligomers and extracted sucrose; (d) hydrolyzing said hemicellulosic oligomers into a hemicellulose sugar stream, wherein said hemicellulose sugar stream comprises said extracted sucrose or a hydrolyzed form thereof; (e) recovering or further processing said hemicellulose sugar stream; (f) recovering or further processing said sucrose-rich stream; and (g) combusting said cellulose-rich solids to produce steam and/or electricity.
