古交矿区8号煤中有机硫含量较高,占全硫的一半左右。首次对8号煤层进行了煤中有机硫的光电子能谱(XPS)测试,采用带能谱和波谱的扫描电镜对2号、7号、8号煤层中不同显微组分中的有机硫进行了测定。结果表明,8号煤中有机硫以多环含硫化合物或噻吩型硫为主;在不同煤层的显微组分中其有机硫含量有差异,但差异不大;同一煤层的显微组分中,不同亚组分的有机硫含量亦不同。
Gujiao mining area No. 8 coal higher organic sulfur content, accounting for about half of the total sulfur. For the first time, the organic sulfur in coal was measured by photoelectron spectroscopy (XPS). The organic sulfur in different microstructures of No.2, No.7 and No.8 coal seam was analyzed by scanning electron microscope with energy spectrum and spectroscopy The determination. The results show that the organic sulfur in No. 8 coal is dominated by polycyclic sulfur compounds or thiophene-type sulfur. The organic sulfur contents in different coal seams are different but not significantly different. The microstructure of the same coal seam In the different subcomponents organic sulfur content is also different.
