摘要： A method of bleaching sulphate pulp without using chlorine-containing bleaching agents. The sulphate pulp is oxygen delignified and can possibly also be ozone delignified to a kappa number below 9.5. Thereafter a pretreatment with complexing agent is carried out for 1-60 minutes, at which the pulp consistency is 1-15 %, the temperature 70-110 DEG C and pH 5-7. The pulp thus pretreated is washed and dewatered to a consistency of 18-40 %. Thereafter peroxide bleaching in alkaline environment takes place in the presence of silicate or an organic complexing agent of the type phosphonic or carboxylic acid.

摘要： At a method of bleaching pulp intended for paper or paperboard the hydrogen peroxide is added as mist in air or vapour to the suspension of the dry pulp, which at high speed flows out of the drier. Also the base used for adjusting the pH value can be added in this way. The disintegration of the peroxide which heretofore rendered dry bleaching difficult is avoided, and high degrees of brightness are achieved.

摘要： A process of bleaching and extracting lignocellulose material for removing lignin using peroxide containing bleaching agents in an acidic environment is disclosed. At least one step of the bleaching process comprises treating the lignocellulose material with a peroxide-containing bleaching agent at a pH of-2 to 7 in the presence of 0.01 -5 g/l of an organic or inorganic complexing agent. Said treatment is followed immediately, without intermediate washing, by alkali extraction of dissolvable lignin.

摘要： Cellulose pulp is bleached with peroxide under superatmospheric pressure in two (or more) stages, with removal of oxygen and reaction gases from the pulp between the stages, About 5-20 Kg/admt hydrogen peroxide is intimately mixed with the pulp and then introduced into a first pressurized vessel in which the pressure is between about 5-15 bar and the temperature between about 80-120 DEG C. Bleaching takes place in the first vessel for about 15-60 minutes while oxygen and reaction gases are formed, and then at least 20 % of (and preferably subtantially all of) the oxygen and reaction gases are removed from the pulp before complete consumption of all of the peroxide. Then the pulp is preferably introduced into a second vessel, additional peroxide, alkali, and steam can be added, and peroxide bleaching continues at a pressure of about 1.1-10 bar and at a temperature of about 90-120 DEG C for between about 30-200 minutes, during which oxygen and reaction gases are formed anew. The majority of the newly formed oxygen and reaction gases -- in fact subtantially all of them -- are separated out, typically upon discharge of the pulp from the second vessel.

摘要： A method for bleaching cellulosic and lignocellulosic pulp using hydrogen peroxide as a bleaching reagent, utilizes a two-step reaction, viz. a short high temperature step at a pressure sufficient to suppress boiling and a longer atmospheric pressure reduced temperature step to consume a substantial portion of the hydrogen peroxide remaining after the short phase. The method includes the steps of introducing pulp (15), at a consistency of 10 %-18 %, to a mixer (100) in which the pulp is heated to a temperature above 100 DEG C; adding sufficient sodium hydroxide to bring the pulp to a pH of 8.5; adding sufficient hydrogen peroxide (36) to equal from about 0.5 %-5.0 %, by weight, of the pulp; passing the pulp through a pressurized reactor column (400) at a rate providing a reaction time in the column of between 1 and 30 minutes; and depositing the pulp in a reaction tower and allowing the reaction to proceed for 1-5 hours until a substantial portion of the residual hydrogen peroxide has been consumed. It may be desirable to introduce the pulp to a mixer and add alkali to reactivate residual hydrogen peroxide by bringing the pulp to a pH of at least 9 between bleaching steps.
摘要翻译：使用过氧化氢作为漂白剂漂白纤维素和木质纤维素纸浆的方法采用两步反应，即，在足以抑制沸腾的压力下的短的高温步骤和较长的大气压降低温度步骤以消耗在短相后残留的大部分过氧化氢。该方法包括将纸浆（15）以10％-18％的浓度引入到其中将纸浆加热至高于100℃的混合器（100）的步骤; 加入足够的氢氧化钠使纸浆的pH值达到8.5; 加入足量的过氧化氢（36）至浆料重量的约0.5％-5.0％; 使纸浆通过加压反应器塔（400），其速率为提供柱在1至30分钟之间的反应时间; 并将纸浆沉积在反应塔中，并允许反应进行1-5小时，直到大部分残余过氧化氢消耗。可能需要将纸浆引入混合器中，并通过在漂白步骤之间使纸浆达到至少9的pH来添加碱以再活化剩余的过氧化氢。
