A Review on the Formation Mechanism of Levoglucosan during Fast Pyrolysis of Cellulose
摘要
Abstract
During the fast pyrolysis of cellulose at medium temperature, levoglucosan ( LG) is the most abundant product. Its formation pathway has gained extensive attention. This paper firstly concludes and compares the different LG formation pathways proposed by scholars from home and abroad. The formation mechanisms of LG are classified into 4 kinds, namely homolysis cleavage mechanism, heterolysis cleavage mechanism, mechanism via glucose and concerted decomposition mechanism. Drawbacks of analyzing reaction mechanism using experimental methods are also pointed out. The paper then summarizes the recent development, i. e. application of the Density Functional Theory ( DFT) . Its contents and results are compared in detail. Finally, future investigation in determination of the LG formation pathway is proposed.关键词
