摘　　要：热解是将固态原料转化为液体燃料、可燃气和焦的重要途径,是实现生物质资源清洁、高效利用的重要技术。将生物质与煤混合共热解是生物质资源利用的重要方法,两者混合热解不仅有助于降低CO_2的排放量,还能有效地解决能源短缺和环境污染带来的问题。文章综述了煤与生物质共热解技术的研究进展,系统地介绍了共热解过程中煤与生物质的相互作用以及热解温度、混合比例、滞留时间、升温速率、矿物质成分、物料粒径和热解反应器类型等因素对热解过程的影响,并对煤与生物质共热解技术的发展前景进行了展望。Pyrolysis is an important way that raw materials is converted to liquid fuels, gas and char, and it is also a significant technology for the clean and efficient usage of biomass resources.Co-pyrolysis of biomass and coal is an efficient method to utilize biomass resources, which can not only reduce the emission of CO2, but also solve the problem of energy shortage and environmental pollution. In this paper, the advance of the co-pyrolysis technology of coal and biomass were reviewed. Meanwhile, the interaction between coal and biomass during the co-pyrolysis process and the effects of co-pyrolysis conditions were also summarized under different pyrolysis temperature,mixing ratio, residence time, heating rate, mineral substance, particle size and type of pyrolysis reactors. Moreover, the prospect of the co-pyrolysis of coal and biomass was further proposed.
