摘　　要：为系统了解国内低阶煤分质利用的产物应用现状和技术发展趋势,介绍了低阶煤分质利用的工艺路线与转化路径,并对煤炭热解产生的3种主要产物(煤焦油、热解煤气、半焦)及其工业化应用现状作了阐述。总结了煤焦油、热解煤气和半焦的利用去向,并剖析了低阶煤分质利用目前存在的关键技术问题,提出了未来重点研究方向,还对发展前景进行了展望。通过分析,认为依据我国煤炭资源的分布、低阶煤的储量及其特点,以及国家对煤炭能源政策的引导,在攻克众多共性关键难题的情况下,低阶煤分质利用宜作为上游工序,同时下游配套煤-电-化一体化项目,这种园区项目组团模式的煤炭分质清洁利用将是实现低阶煤利用互利共赢的最佳方式。In order to know systematically the products＇ application status and the trends of technology developmentoflow rank coal quality -based utilization in China, introduces the process route and conversion path of low rank coal quality-based utilization briefly, and ex- pounds the three main products （coal tar, pyrolysis gas, carboeoal） produced by pyrolysis and their industrial application status. Emphatically sumed up how to use coal tar, pyrolysis gas and carbocoal, and analysed the key technology problems of low rank coal quality-based utilization at present,put forward the research directions in future, also on the development prospects were looking forward. Through the analysis, that according to the distribution of coal resources in China, reserves and characteristics of low rank coal, as well as the guidance of the national to the coal energy policy, in conditions of solving the common key problems,low rank coal quality-based utilization should be taken as the upstream process, at the same time, downstream of coal-electricity-chemical industry integration project, this park project group mode forthe clean coal quality-based utilization will be the best way to achieve mutual benefit and win-win use of low rankcoal.
