摘要： A process for digesting lignocellulosic material. Lignocellulosic material is introduced into a digestive zone along with a liquid composed of an ester with an organic lignin solvent capable of dissolving lignin, and water. The lignocellulosic material is digested at a temperature of 0°C to 230°C for a period of time sufficient to solubilize the lignin in the ester and the solvent. The process of the invention reduces the amount of water in the digestive zone to inhibit the hydrolysis of the cellulose, accelerate the delignification and provide a more economical chemical recovery system.
摘要翻译：一种消化木质纤维素材料的方法。将木质纤维素材料与由具有能够溶解木质素的有机木质素溶剂和水组成的液体一起引入消化区。木质纤维素材料在0℃至230℃的温度下消化足以使木质素溶解在酯和溶剂中的时间。本发明的方法减少了消化区中的水分，以抑制纤维素的水解，加速脱木质素并提供更经济的化学回收系统。

摘要： The pulp to be washed is fed between the rotating drum (1) and the pressing roll (2) inside it, so that pulp passes along a spiral-formed track around the pressing roll (2), being thereby pressed several times. Washing liquid (7) is fed to the pulp at one or several points along its track of movement, between the pressings and/or at the pressing position. Washing thus takes place partly as a diffusion and partly as a displacement washing process. Washing is efficient and brings the breaking of pulp fibers down to a minimum.
摘要翻译：待清洗的纸浆在其内部的旋转滚筒（1）和压榨辊（2）之间进给，使得纸浆沿着挤压辊（2）周围的螺旋状轨迹通过，从而被按压数次。洗涤液体（7）沿其运动轨迹，压力和/或按压位置之间的一个或几个点被送入纸浆。因此，洗涤部分地作为扩散部分地进行，部分地作为位移洗涤过程。洗涤是有效的，并将纸浆纤维的破碎降至最低。

摘要： Brown stock washing of wood pulp is improved by adding a water-soluble cationic polymer to the wash water. The cationic polymer reacts with lignin solution present in the larger channels in the pulp mat to give a precipitate which lowers the flow rate of wash water through the larger channels. A more efficient wash water usage is obtained.

摘要： A bleached organosolv pulp is obtained in a process comprising the steps of bleaching an organosolv pulp with ozone (26), washing the ozonated pulp with an aqueous solution of a lower alkyl alcohol (30) to remove lignin dissolved therein, removing filtrates of the alcohol wash solution from the washed pulp and returning the removed filtrates for reuse in the process (13, 28). The ozonated washed pulp is further bleached (34) to yield a fully bleached pulp with a brightness of over 90 ISO without the use of chlorine-containing chemicals.

摘要： A system for dewatering/washing wood pulp and also for bleaching the same. Pulp from a digester is directed into a dewatering/washing apparatus (10) which comprises a high pressure vessel (12) in which there is a table assembly (24) having a perforate support surface for receiving the pulp thereon. A pressure differential is applied across the table assembly so that liquid is removed from the pulp. Also, a processing chemical and/or compound for bleaching is directed into the pulp at a final stage in the washer so as to be retained in the pulp. The pulp is then directed to a pressurized processing vessel where the compound and/or chemical reacts with the pulp. The pulp so treated in the processing vessel is then directed through a second washing station where the pulp is dewatered and has a compound and/or chemical introduced thereon, after which the pulp is transmitted to a second pressure vessel. This process is continued until the bleaching process is completed.

摘要： A wood pulp slurry (17, 73, 123, 209) is treated with oxygen (89, 429, 212) in a mill with little change to the process or structure of the mill. No special pressure tanks are required. The consistency of the pulp need not be altered for the treatment step. It may be treated at the usual process consistency of the pulp; e.g.; it may be treated at the usual consistency of the pulp leaving a washer or subsequent steam mixer (86, 426, 206) without additional dewatering or additional dilution. The oxygen is added into a closed section of the system so that it cannot immediately vent to the atmosphere. Alkali (85, 425, 207) should also be present when the oxygen is mixed with the slurry. The mixing (88, 428, 211) should occur near to the point of oxygen addition. The pulp is treated with oxygen several times during a sequence. Some sequences are O-X-O and O-O-X-O in which X may be a hypochlorite, a peroxide or ozone, or chlorine, chlorine dioxide, combinations of chlorine (438) and chlorine dioxide (471), hypochlorite, peroxide or ozone. The sequence may be followed by a D stage (232). Specific mixer designs are also disclosed.
摘要翻译：在磨机中用氧气（89,429,212）处理木浆浆料（17,73,123,209），与轧机的工艺或结构几乎没有变化。不需要特殊的压力罐。对于处理步骤，不需要改变纸浆的稠度。可以按照纸浆的通常工艺一致性进行处理; 例如。; 可以以离开洗涤器或随后的蒸汽混合器（86,426,206）的纸浆的通常稠度进行处理，而无需额外的脱水或额外的稀释。将氧气加入系统的封闭部分，使其不能立即排放到大气中。当氧气与浆料混合时，也应存在碱（85,425,207）。混合（88,428,211）应发生在加氧附近。在序列期间，用氧气处理纸浆几次。一些序列是O-X-O和O-O-X-O，其中X可以是次氯酸盐，过氧化物或臭氧，或氯，二氧化氯，氯（438）和二氧化氯（471），次氯酸盐，过氧化物或臭氧的组合。该序列之后可以是D阶段（232）。还公开了特定的混合器设计。
