查询词典 delignification

The residual lignins extracted from both the original and oxygen-delignified softwood kraft pulp and those isolated from the effluent of oxygen delignification were subjected to pyrolysis in the presence of tetramethylammonium hydroxide.

从针叶木硫酸盐原浆、氧漂浆以及氧漂后的废液中分离出残余木素，在四甲基氢氧化铵存在下，采用裂解气相色谱-质谱联用的方法研究了氧漂过程中木素分子结构的变化。

Oxidation veratryl alcohol by LAC/NHA or HBT was 0 degree reaction, but the coefficient of the reaction with NHA is bigger than that with HBT, which means that NHA is more efficient for LMS delignification than HBT.

此外，还比较了NHA和HBT作为介体的LMS体系氧化非酚型木素模型化合物藜芦醇的动力学规律，结果表明藜芦醇的氧化与时间呈直线关系，此氧化反应为0级反应，不过使用NHA和HBT作为介体时，藜芦醇的氧化速度常数有所不同，使用NHA时，藜芦醇氧化的速率常数大，反应速度快。

For violuric acid mediated electrochemical delignification the electrode of Ti/RuTiO_x had best

VIO为介体的电化学脱木素的最优工艺为：VIO1.8mmol／L，电压2.5V，时间5h，pH值4.5，温度50℃，Na_2SO_40.05mol·L~(-1)。

While the up-flow reactor is the key equipment in medium- and high-consistency clean bleach process, including oxygen delignification、hydrogen peroxide bleach、chlorine dioxide bleach、 ozone bleach, the flow characteristics of the medium consistency pulp in up-flow reactor have significant impact on the quality and the efficiency of the bleach reaction. In this work, a series of equipments are designed and manufactured for a systematic and deep study on the flow characteristics of the medium consistency pulp in up-flow reactor.

而升流式反应器是中高浓清洁漂白工艺（包括氧气脱木素、过氧化氢漂白、二氧化氯漂白、臭氧漂白等工艺）中的大型关键设备，中浓纸浆在升流式漂白反应器中的流动特性与漂白反应的质量、效率都有密切关系，因此本研究自行设计和制造了相关的实验设备，对中浓纸浆在升流式反应器中的流动特性进行了较为系统、深入的研究。

Measurement of Ligninolysis The delignification of a solid lignocellulosic substrate is often assessed by the simple procedure of removing its low molecular weight components by extraction, weighing the leftover woody residue, degrading the remaining polysaccharide component with strong acid, and then reweighing the leftover insoluble lignin, which is chemically modified and referred to as Klason lignin.

木质素降解的测量对固体的木质纤维素基片进行去木质反应之前，先要进行一个简单的步骤，即，用萃取去除低分子量的成分，称重剩余木质残渣，用强酸降解剩余的多糖成分，称重剩余的不可溶木质素，这种木质素已经从化学成分上被改变，并被称为克拉森木质素。
