Abstract
The present invention relates to methods of processing lignocellulosic material to obtain hemicellulose sugars, cellulose sugars, lignin, cellulose and other high-value products. Also provided are hemicellulose sugars, cellulose sugars, lignin, cellulose, and other high-value products.
Claims20
A method of separating xylose from a biomass-derived sugar stream, the method comprising:
- fractionating the biomass-derived sugar stream using a chromatographic separation system comprising a weak base anion (WBA) exchange resin;
- and
- collecting a fraction containing xylose in a ratio to total dissolved sugars (DS)>0.40 weight/weight.
