摘要:

纤维素是生物质的重要组成部分,而热解技术是一种具有应用前景的高值转化技术,利用纤维素热解来生产各种燃料和高值化学品对未来化工产业的发展具有重要意义。对纤维素热解机理和模型进行研究有助于对纤维素热解过程和热解产物进行分布调控。因此,以纤维素的热解机理和热解动力学模型为基础,概括了纤维素热解过程中热解产物(热解气、热解炭、热解油) 的应用,进行了以热解油为基础,选择性生产高值化学品的研究。分析不同催化剂对于制备左旋葡萄糖酮(LGO)、1-羟基-3,6-二氧杂双环[3.2.1]辛-2-酮(LAC)、糠醛、芳烃和酚类的应用,总结纤维素催化热解制备这些增值化学品的最佳条件,最后指出纤维素热解制备高值化学品研究中存在的问题,并对以后的研究工作进行了展望。

Abstract:

Cellulose is an important component of biomass, and pyrolysis technology is a high-value conversion technology with promising application prospects. It is of great significance to use cellulose pyrolysis to produce various fuels and high-value chemicals for the development of chemical industry. The study on cellulose pyrolysis mechanism and model is helpful to control the cellulose pyrolysis process and distribution of pyrolysis products. Therefore, based on the cellulose pyrolysis mechanism and kinetic model, the applications of pyrolysis products (pyrolytic gas, pyrolytic carbon, pyrolytic oil) in the process of cellulose pyrolysis are summarized, especially the selective production of high-value chemicals produced based on pyrolysis oil. The effects of different catalysts on the preparation of levoglucosenone (LGO), 1-hydroxy-3,6-dioxabicyclo [3.2.1] oct-2-one (LAC), furfural, aromatics and phenols were analysed, and the optimal conditions for the preparation of these value-added chemicals from catalytic pyrolysis of cellulose were investigated. Finally, the problems in the preparation of high-value chemicals from cellulose pyrolysis were pointed out, and the future of the research was prospected.
