| Abstract: | Black liquor of low effective alkali and high sulfidity is used in the pretreatment stage and cooking stage of the RDH process.With appropriate black liquor addition in the two stages, selectivity of delignification is found to have been promoted, resulting in reducing degradation of carbohydrates, hence improved pulp quality. |
