摘要： A process for the bleaching of chemical pulp, wherein the initial bleaching of the pulp comprises a first chlorine dioxide treatment (D0) and a following alkaline treatment with oxygen and hydrogen peroxide (EOP), which stages are separated from each other with a washing stage, and a treatment of the pulp to reduce the content of transition metals of the pulp prior to said peroxide treatment. The process is characterized in that alkali is added to the pulp after addition of chlorine dioxide in the D0 stage to adjust the pH of the pulp to neutral or basic (N stage) prior to the washing stage following the chlorine dioxide stage, whereby the initial bleaching comprises the sequence D0N EOP.

摘要： Final chlorine dioxide bleaching of lignocellulosic materials is most effective at a near-neutral pH but present industrial practice typically targets a final pH of between 3.5 and 4.0 because of the difficulty in achieving and maintaining near-neutral pH cost effectively. The in situ formation of bicarbonate before the addition of chlorine dioxide provides a way of maintaining the required near-neutral pH. Near-neutral final chlorine dioxide bleaching also produces a bleached pulp that is in a state that responds more effectively to fluorescent whitening or optical brightening agents.
摘要翻译：木质纤维素材料的最终二氧化氯漂白在近中性pH下是最有效的，但由于难以有效地实现和维持近中性pH的成本，因此目前的工业实践通常将最终pH值定在3.5和4.0之间。在添加二氧化氯之前，原位形成碳酸氢盐提供了维持所需的近中性pH值的方式。近中性的最终二氧化氯漂白还产生漂白纸浆，其处于对荧光增白剂或荧光增白剂更有效响应的状态。

摘要： The invention concerns a method for bleaching cellulose pulp having an MC consistency in a first step with chlorine dioxide in a bleaching sequence with several bleaching steps. The pulp is bleached in this first chlorine dioxide step in a first phase at a lower temperature of 60 +/- 10 °C during a retention time of from 30 seconds to 30 minutes, after which the pulp is heated by at least 10 °C to a reaction temperature of 90 1/- 10 °C for a second phase, which has a retention time of 60-200 minutes. With this process modification of a first chlorine dioxide step, an efficient destruction of undesired organic acids is obtained, while at the same time improved viscosity/strength of the pulp can be obtained of the finally bleached pulp with a whiteness of approximatels 90 % ISO.
