Investigating the effect of using oxygen delignification process on kenaf bast kraft pulp properties [PDF]

open access: yesتحقیقات 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.
