为从煤的本体组成结构方面来阐述煤中硫的赋存与分布规律，以高含有机硫的新峪焦精煤为对象，采用萃取反萃取的煤全组分分离方法和XPS、GC／MS等分析技术，对原煤和各族组分中的不同形态无机硫和有机硫含量进行了研究，重点考察了有机硫在煤有机质本体中的赋存规律。结果表明，无机硫的分布主要依赖于其自身在煤主体中的粒径大小和密度高低，与煤族组分本身结构关联较小。无论是原煤还是族组分，其有机硫均以噻吩型硫占主导；共轭结构为主的分子外环境，使共轭结构类有机硫的电子结合能降低，而使脂肪结构类硫的电子结合能升高，反之亦然。有机硫在煤中分布总体均衡，不会因为族组分结构不同而产生较大差异；但有机硫的类型硫赋存比例则与族组分本身的结构特征有所关联，不过其差别相对较小。轻质族组分中只含有一种有机硫小分子化合物，且相对丰度较小。

This paper illustrates the occurrence and distribution of sulfur in coal from the perspective of composition and structure of the coal body.With the organic sulfur-rich Xinyu clean coking coal as the sample, and the method of separating all group components from coal through extraction and stripping process as well as X-ray photoelectron spectroscopy ( XPS ) and gas chromatogrpa hy/masss pectrometer ( GC/MS) analysis techniques, the content of inorganic sulfur and organic slu fur of diffre ent forms in raw cola and various group components isstudied andt he occurrence of organic sulfur in organic matter of coal is carefully observed.The results show the distribution of inorganic sulfur is mainly dependent upon its particle siez and density in coal and has less relationship wti h the structure of group components of coal.Thiophene sulfur ist he major form fo o rganic sufl ur either in raw cola or group components.The ext ernal envri onment of molecules dominated by conjugated structure can derc ease the elector n binding energy of ogr anic sulfur in conjugated structru e, whiel incrae se that of us lfur in aliphatic structure.Th e distribution of organic sulfuri n coal si balanc ed as a whole and will not be signifiac ntly infleu nced by ts rucut ral differne ces of group components. Howve er, the occurrence of organic sulfur compounds is assocai ted with the structure of group components, showing relatively small difference.And there is only one type of small molce ule orag nic sulfur compounds in light component, with small abundance.
