Investigating the effect of using oxygen delignification process on kenaf bast kraft pulp properties [PDF]
تحقیقات علوم چوب و کاغذ ایران, 2018 The first act to ameliorate bleaching process is the major elimination of lignin. Actually, the use of oxygen delignification stage before bleaching process is the essential stage in improving bleaching process and reducing process emission.

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 ...
