Abstract

Water post-hydrolysis of birch Kraft pulps in a flow-through reactor allows their conversion to viscose-grade pulps while recoverying the extracted sugars as xylooligosaccharides (XOS). Up to 240 ºC, increasing extraction temperature favors the removal of xylan over the degradation of cellulose. Beyond 240 ºC, increasing temperature has negligible effects on the selectivity of xylan removal. The recovery of XOS from the hydrolysates increases with flow rate due to limited formation of sugar degradation products.
