heal.abstract	The combination of acid prehydrolysis with chemical delignification is examined as a potential method for the chemical fractionation of lignocellulosic biomass. Experiments with wheat straw show that hemicellulose can be quantitatively separated by prehydrolysis; however, the structure of the residue is substantially modified. Delignification of this residue with the conventional, alkaline methods (soda, kraft) leads to significant losses of polysaccharides and a degraded cellulose. The efficiency of the separation can be increased by an unconventional delignification, such as chlorination by chlorine gas. In this case, the sugar losses are minimal and further degradation of cellulose during delignification can be avoided, while lignin is quantitatively recovered from the pulping liquors. © 1982 American Chemical Society.	en
