1) Oxygen delignification of populus kraft pulp is studied.

2) Comparative Studies of Delignification Caused by Ganoderma Species.

3) The factors affecting oxygen delignification of fast - growing eucalyptus kraft pulp with kappa number 17.

4) The topochemistry of alkaline delignification of grasses and its effects on the pulping technique were also discussed.

5) The purpose of this study is to find the delignification rate equation of pennisetum ( napier grass) by Soda pulping method.

6) These results confirmed quantitatively that lignin oxidation is essential for the delignification during oxygen bleaching.

7) The purpose of this study is to find the delignification rate equation of pennisetum (napier grass) by Soda pulping method. The initial concentration of sodium hydroxide is 1M.

8) Experimental results showed that the wheat straw pulp and wood pulp were different in delignification characteristics.

9) Then ozonic -hydrogen peroxide bleaching were carried out and the results show that the higher of Kappa number,[http:///delignification.html] the poor of the delignification selectivity and the lower of brightness rising.

10) Research was conducted on the AS AQ pulping and the subsequent oxygen delignification of wheat straw.
