Claims15
A method for preparing a purified hemicellulose composition comprising:
- providing a lignocellulosic biomass;
- combining the lignocellulosic biomass with water;
- activating the lignocellulosic biomass and water using conditions comprising a temperature and a pressure to form an activated cellulose stream;
- washing the activated cellulose stream to form a washed activated cellulose stream and a soluble extract, wherein the soluble extract comprises hemicellulose;
- and
- purifying the soluble extract to obtain a hemicellulose composition comprising:
- (a) about 82% to about 92% by dry weight of xylan, wherein said xylan comprises about 70% to about 99% of arabinoxylan;
- (b) about 8% to about 9% by dry weight of xylo-oligosaccharide;
- and
- (c) about 4% to about 5% by dry weight of xylose.
