木质纤维素液化制备植物基多元醇研究进展

Research progress in perparation of plant-besed polyols by the liquefaction of lignocellulose

介绍了木质纤维素的组成及各组分的液化机理,综述了溶剂热液化催化剂的研究现状,催化效果及缺陷。木质纤维素结构复杂,纤维素具有高结晶度,不利于木质纤维素的液化,为提高液化效率,提出了对木质纤维素进行预处理的解决方法,包括物理预处理、生物预处理和化学预处理。

The composition of lignocellulose and liquefaction mechanism were introduced,and the research status,effects and defects of different catalysts for solvent thermal liquefaction were also reviewed.Due to the complex structure and high crystallinity of lignocellulose,it is not conducive to liquefaction,and the pretreatment of lignocellulose was proposed,including physical pretreatment,biological pretreatment and chemical pretreatment.
