| Abstract: | Chlorine dioxide is used as bleaching agent for pulp bleaching, has the characteristics of producing the pulp with high yield, and high whiteness, the waste water with low chrominance and toxicity. Chlorine dioxide is the main bleaching agent of element chlorine free bleaching process for chemical pulp. In this paper, the development course and preparation method of chlorine dioxide were described, the production technology and cost of chlorine dioxide by methanol method and integrated method were compared, and the localization process of chlorine dioxide preparation technology was introduced. |
