Effect of Wet Storage on High Yield Pulping with H₂O₂-CoSO₄

Abstract:

In this paper, the effect of residual chlorine of hypochlorite (H) on high yield pulping with H₂O₂/CoSO₄of wet stored bagasse was studied. Compared with control sample, the pulp of the bagasse wetstored with H or Ho (without residual chlorine) bleaching waste water had better pulping yield and strength, but the pulp optical property was lost seriously. If it had no requirement on the brightness, the wet storage with H or Ho bleaching waste water was a good method to improve the pulp strength and save clean water. In addition, the wet storage of bagasse using the H bleaching waste water without residual chlorine, the pulping properties was more stable than that of the wet storage using H bleaching waste water with residual chlorine. To the wetstorage with Ho bleaching waste water, the ideal treatment time was 16day.
