摘要
本文利用ＦＴＩＲ分析及计算、有机溶剂抽提，研究了神府煤不同煤岩组分的结构特征。得出了镜煤的芳构化程度较低，分子中含有较多的烷基侧链及阳离子类基团，而丝炭的芳构化程度较高，分子中含有较多的活性氧。这一结论，对于认识煤岩组分的性质。
By means of FTIR analysis and methematic calculation, organic solution extraction, and the like, this paper deals with the structural characteristics of various lithotypes of Shenfu coals It shows that the vitrain contains low aromaticity and more aliphatic side chains and cationic groups, such as NH, NH 2, etc Fusain contains high aromaticity and more active oxygen groups. These findings are significant in understanding of the characteristics of coal petrographic constituents and in separating and enriching these constituents.
