摘要
研究煤岩显微组分的性质有助于了解煤的起源和分子结构,对研究和预测煤的热加工反应性,实现煤的高效洁净和高附加值转化具有重要的意义.综述了近年来国内外对煤的岩相显微组分性质的研究,着重介绍了显微组分的化学组成及分离分析技术,显微组分的热解、气化、燃烧和加氢液化特性及显微组分对煤溶剂萃取的影响,并指出了煤岩显微组分研究的重要意义.
It is necessary for understanding the genesis and molecular structure of coals to study the characteristics of coal macerals,and it is very interesting for investigating and predicting the thermal processing reactivity of coals,and clean,effective and high value-added utilization of coals.This paper reviewed the new advances in macerals of coals.The chemical composition and separation and analyses technology of macerals,the characteristics of pyrolysis,gasification,combustion and hydroliquefactiton of macerals,and the effects of macerals on solvent extraction of coal were mainly discussed.The importance of macerals research was pointed out.
