摘要

低阶煤直接燃烧效率低且污染严重，对煤炭资源造成极大浪费，实现低阶煤的高效清洁利用对缓解我国能源紧缺问题具有重要意义。微波热解技术具有能耗低、热解效率高和安全环保等优点，该技术为低阶煤热解提供了新思路。首先总结了微波热解技术原理及其在煤炭（主要针对低阶煤）热解方面的应用概况；然后分析了影响煤炭微波热解的因素，主要包括煤炭性质、微波吸收剂、热解气氛和共热解；最后对低阶煤微波热解技术发展面临的问题和未来研究方向进行了分析和展望。

Abstract

The efficiency of direct combustion of low rank coal is low and pollution is serious

which causes great waste of coal resources. Realizing efficient and clean utilization of low rank coal is of great significance to alleviate energy shortage in China. Microwave pyrolysis technology has the advantages of low energy consumption

high pyrolysis efficiency and safety and environmental protection

which provides a new idea for low rank coal pyrolysis. Firstly

the principle of microwave pyrolysis technology and its application in coal (mainly low rank coal) pyrolysis were summarized. Then the factors affecting coal microwave pyrolysis were analyzed

including coal properties

microwave absorbers

pyrolysis atmospheres and co-pyrolysis. Finally

the problems and future research directions of low rank coal microwave pyrolysis technology were analyzed and prospected.
