Influence of xylan content on the oxygen delignification performance of eucalypt kraft pulps as studied using prehydrolysis and xylanase treatments [PDF]

BioResources, 2012
Common metrics for evaluating the efficiency of oxygen delignification include the kappa number and Klason lignin content. As a change in xylan content often leads to a change in HexA content, the kappa number must be corrected for the HexA contribution ...
