【摘要】 木质素的降解往往会伴随其解聚中间体的再聚合,从而增加进一步降解的难度,严重影响木质素的降解率。因此,有效抑制中间体的再聚合是提高木质素降解率的关键。抑制再聚合可以通过改变木质素降解体系的反应路径或者反应环境来达到。主要从抑制或减少木质素再聚合的角度出发,综述了对反应体系添加阻聚剂、缩短反应停留时间和提供温和的反应环境3种有效方法来提高木质素的降解率。更多还原

【Abstract】 The degradation of lignin is freguently accompanied by the repolymerization of its intermediates, which increases the difficulty of further degradation and seriously affects the degradation efficiency of lignin. Therefore, effectively inhibiting the repolymerization of intermediates is the key to improve the degradation efficiency of lignin. Inhibiting repolymerization can achieve the purpose of inhibiting polymerization by changing the reaction path or reaction environment of the lignin degradation system. From the perspective of inhibiting or reducing lignin repolymerization, the thesis summarized three effective methods to increase the degradation rate of lignin by adding inhibitors to the reaction system, shortening the reaction residence time and providing a mild reaction environment.更多还原
