APPLICATION OF AQ IN OXYGEN DELIGNIFICATION OF WHEAT STRAW SODA PULP

摘要：

Oxygen delignification of wheat straw soda pulp with AQ addition was studied. Through a L9(34) orthogonal test, the effects of alkali charge, oxygen pressure, maximum cooking temperature and holding time at the maximum temperature were evaluated. The optimal conditions were as follows: alkali charge on oven dry pulp (as NaOH) was 3％, with oxygen pressure of 0.5MPa, maximum temperature of 120°C and holding time at the maximum temperature of HOmin. Compared with the corresponding conventional oxygen delignification of wheat straw soda pulp, the oxygen delignification with AQ addition produced pulp with very close kappa number but higher yield, and its viscosity and brightness were remained in high level.
