Abstract

Based on a comparison of elemental analysis data and IR- and ¹³C NMR-spectroscopic data, principal differences in the chemical compositions of lithotypes isolated from Kuznetsk Basin coals of different ranks based on characteristic properties were established. The influence of the chemical composition and physical properties (porosity and surface topography) of the lithotypes on the wettability of their surfaces with water was found. It was shown that coals with high concentrations of fusainized components have increased surface hydration due to developed porosity, pronounced surface texture, coal matter mineralization, and the presence of aromatic fragments with substituted oxygen heteroatoms, which have greater hydrophilicity than that of hydrocarbon structures, in the organic matter of coal (OMC).

煤表面润湿性对岩相组成的依赖性

摘要

通过对元素分析数据，IR和¹³ C NMR光谱数据进行比较，基于特征性质，确定了从不同等级的库兹涅茨克盆地煤中分离出的岩性化学组成的主要差异。发现岩石型的化学组成和物理性质（孔隙度和表面形貌）对其表面在水中的润湿性的影响。结果表明，由于孔隙率的增加，表面纹理的明显变化，煤物质的矿化作用以及存在取代氧杂原子的芳烃碎片（其亲水性比烃结构的亲水性大），高浓度富硫化成分的煤具有更高的表面水合作用。煤炭的有机物（OMC）。
