2020-6-8 · The potential to modify pulp and paper properties by oxygen delignification was assessed by looking beyond the ordinary purpose of oxygen delignification. Pulps with the same kappa number were obtained by both pulping and the combination of pulping and oxygen delignification, and the mechanical and chemical properties were compared. The oxidation of pulp components leads to an increase in .

In the Kraft pulping, the pulp obtained was subjected to bleaching processes in. order to assess the chemical reagent consumptions and to achieve a high ISO. brightness. Finally, the "soda" pulp bleaching by a TCF sequence was studied, using an. enzymatic pretreatment, in order to assess the evolution of brightness and. colorimetric properties.

2016-8-9 · The three pulps were screened, washed, blended and dewatered to give a single large batch of pulp having a kappa number of 30.3. The kappa numbers before blending were 28.1, 31.6 and 32.3. The black liquors were combined, tested to determine that the solids content was 13%, and stored cold for use in the bleaching experiments.

2020-7-14 · A general description of this goal is to deliver pulp with the lowest Kappa number to a bleach plant that still maintains the required pulp strength and avoids sharply dropping the pulp yield (Pikka et al. 2000). It is necessary to establish an integrated optimization model for the chlorine dioxide bleaching process to achieve this goal.
