山西阳煤二矿无烟煤元素赋存特征的XPS研究

采用X射线电子能谱解析山西阳煤二矿无烟煤碳、氢、氧、氮和硫的赋存特征。结果表明：山西阳煤二矿无烟煤中碳的主要赋存形式为芳香碳和脂肪碳，碳碳单键的含量最高占82.34%，无烟煤存在大量烷基侧链，醚基氧和羟基氧占氧元素的82.51%。氮元素主要以吡咯氮和吡啶氮等有机氮形式存在，其中大部分存在于煤分子边缘；硫元素主要存在形式为有机硫，噻吩、砜和亚砜分别占35.34%和32.3%，硫醇和硫醚占3.39%，无机硫占25.97%。

XPS Study on the occurrence characteristics of anthracite elements in Yangmei No. 2 mine, Shanxi Province

the occurrence characteristics of carbon, hydrogen, oxygen, nitrogen and sulfur in anthracite of Shanxi Yangmei No. 2 coal mine were analyzed by X-ray electron spectroscopy. The results show that the main forms of carbon in anthracite of Shanxi Yangmei No. 2 coal mine are aromatic carbon and fatty carbon, the content of carbon carbon single bond is the highest, accounting for 82.34%, anthracite has a large number of alkyl side chains, and ether oxygen and hydroxyl oxygen account for 82.51%. Nitrogen mainly exists in the form of organic nitrogen such as pyrrole nitrogen and pyridine nitrogen, most of which exist at the edge of coal molecules; The main forms of sulfur are organic sulfur. Thiophene, sulfone and sulfoxide account for 35.34% and 32.3% respectively, mercaptan and sulfide account for 3.39% and inorganic sulfur account for 25.97%.
