摘要
中国低变质烟煤储量丰富,中低温热解是低变质烟煤极佳的利用方式,介绍了煤热解、煤热解过程的影响因素及煤热解的研究现状,重点梳理了煤热解机理的发展及热解机理的最新研究成果,现阶段实现了对煤热解过程的定量描述,对煤热解过程中的二次反应认识也得到了一定的细化,继续加大煤热解的基础研究将为中国煤炭资源的高效清洁利用指出方向,实现煤的定向热解和产物调控,更好地指导工业实际应用。
Low-rank bituminous coal is abundant in China,and medium-low-temperature pyrolysis is an excellent way toutilize low-rank bituminous coal.This paper mainly introduces coal pyrolysis,the influencing factors of coal pyrolysis process and the latest research results of coal pyrolysis mechanism.At present,the quantitative description of coal pyrolysis process has been realized,and the understanding of the secondary reaction in coal pyrolysis process has been refined to a certain extent.Further increasing the basic research on coal pyrolysis will point out the direction for the efficient and clean utilization of coal resources in China and will realize the directional pyrolysis of coal,and better guide the practical application of industry.
