Present Situation and Analysis of Macerals Separation and Utilization Technologies

随着石油资源的紧缺和煤炭加工带来的环境污染日趋严重，煤炭资源的清洁和高效利用成为当下的热点课题。煤岩有机显微组分可以将煤中有用的有机质主要分为三种：壳质组、镜质组和惰质组。分离煤中显微组分并根据显微组分不同的特性进行煤炭深加工如热解、气化和液化，可以有效提高煤炭利用率且缓解石油资源短缺的现状。本文对当前煤岩有机显微组分的分离和应用技术研究进展进行了介绍，分析了其发展方向和前景。 Along with serious environmental pollution caused by coal combustion as well as the scarcity of oil resource, highly efficient and clean utilization of coal resource has becoming the immediate research focus. The useful organic matter in coal can be classified into three coal maceral types: exinite, vitrinite and inertinite. The separation and the further processing technologies such as pyrolysis, gasification and liquefaction of macerals according their different features could improve coal utilization rate effectively and lighten oil resource’s shortage. In this paper, the research progress of macerals separation and utilization technique is introduced and the further development and improvement are analyzed.
