| Abstract:The existing cotton linter hydrogen peroxide one-step pulping and bleaching process realized simultaneously degreasing and bleaching, however due to the difference of degreasing temperature and bleaching tempreature, it would cause low utilization rate of peroxide. This paper proposed to adorpt two-step process, in which cotton linter was degreased at first, then bleached with peroxide. This process could improve hydrogen peroxide utilization rate and reduce COD discharge. |
