摘要： A pulp production process can produce pulp at high yield without using sodium sulfide and high-temperature/high-pressure conditions if compared with the Kraft process and also collect lignin. Pulp is produced by processing wood chips for hydrophlicization at room temperature, using a dilute caustic soda aqueous solution, selectively partially modifying lignin in dilute nitric acid and digesting the wood chips by means of a dilute caustic soda aqueous solution under the atmospheric pressure. Lignin is agglomerated and sorted out from the isolated black liquor.

摘要： The method solves the problem of delignifying technical cellulose pulp in a selective manner which will result in very low residual contents of lignin in the pulp and a correspondingly high quantity of lignin dissolved in spent liquors, which are recovered in the chemical recovery system of the pulp mill. The method comprises activating liquid-containing lignocellulosic material in the presence of nitrate with a gas that contains nitrogen dioxide, followed by the alkaline delignification of the lignocellulosic material, and measuring the acidity of the liquid accompanying the material on at least one occasion during the activation. The method is characterized in that the acidity of the liquid is measured subsequent to bringing the time derivative of the nitrate concentration of the liquid, expressed as millimols per liter of liquid per minute, to a level beneath +0.2, and by using the measured acidity value to establish the optimum amount of mineral acid for continuation and termination of the activation, and by charging the whole of this quantity or a part of this quantity of mineral acid to the lignocellulosic material.
摘要翻译：该方法解决了以选择性方式脱木质纤维素纸浆的问题，这将导致纸浆中木质素的残留含量非常低，并且相当大量的溶解在废液中的木质素在纸浆的化学回收系统中回收磨。该方法包括在硝酸盐存在下使含有二氧化氮的气体活化含木质纤维素材料，然后在木素纤维素材料的碱脱木质作用下，在活化期间至少一次地测量伴随该物质的液体的酸度。该方法的特征在于，在将液体的硝酸盐浓度的时间导数（以毫升/分每分钟液体表示）达到+0.2以下的水平之后，测量液体的酸度，并且通过使用测量的酸度建立最佳量的无机酸以继续和终止活化，并将这一量或一部分无机酸的总量加入到木质纤维素材料中。

摘要： A system for controlling a processor having at least one sampling port connected to a stage of the processor in order to sample a reactant product from the processor. The system includes a controller configured to control a processing parameter of the processor based on measurements of at least one property of the reactant product such that changes to the processing parameter maintain a target value for the at least one property of the reactant product. The system further includes a dead time compensator. The dead time compensator is configured, based upon a prescribed dead time related to a time before at least one effect of at least one change to the processing parameter is fully realized, to evaluate the reactant product to determine if the effect has been realized at a plurality of sequential times offset from the dead time.

摘要： Two stage hydrolysis of lignocellulosic material, conditions during the first stage being such as to hydrolyze or depolymerize the hemicellulosic component without substantial degradation of resulting monosaccharides, conditions during the second stage being such as to hydrolyze the cellulose to glucose without substantial degradation of the glucose. The solids left after first stage hydrolysis are disintegrated mechanically thereby greatly facilitating second stage hydrolysis. Hydrolysis in both stages is preferably accomplished by the use of nitric acid. The pH retention time and temperature in both stages are selected to maximize production of the desired monosaccharide or monosaccharides.
