生物质定向快速热解制备左旋葡聚糖和芳烃的研究进展

Progress of Biomass Fast Pyrolysis to Produce Levoglucosan and Aromatics

木质纤维素快速热解转化为高价值的左旋葡聚糖和芳烃是国内外的研究热点之一。目标产物的选择性低是限制其工艺发展的关键问题。本文介绍了木质纤维素的组分,并讨论了其组分对热解产物的影响,提出预处理-催化热解的生物质炼制技术,可实现快速热解产物的灵活可调,定向转化为左旋葡聚糖和芳烃。

Conversion of renewable lignocellulose into value-added levoglucosan and aromatics by fast pyrolysis has attracted lots of attention.The low selectivity of the target product is the key problem which limits the development of this process.In this paper,the composition of lignocellulose and its effect on the distribution of pyrolysis products are discussed.The pretreatment on lignocellulose prior to fast pyrolysis and catalytic pyrolysis technology can improve the yields of levoglucosan and aromatics.
