基于煤密度特性的差异，探讨煤中主要有害元素硫的结构和赋存形态，有利于煤精细加工新技术的开发。采用XPS分析方法研究我国炼焦煤主产地山西不同密度煤样中有机硫的赋存形态及相对含量。结果显示，煤样中有机硫形态主要有硫醇（醚）、噻吩、（亚）砜三类，有机硫形态随煤密度不发生变化，噻吩硫相对含量随煤密度增大而降低，其它两类有机硫总量随煤密度增大而升高。

The structure and occurrence of sulfur in coal of different density were discussed , and the study is ad-vantageous to development of new technology for coal fine processing .The occurrence and relative contents of or-ganic sulfur in different density coal samples from Shanxi Province , where is the major site of coking coal produc-tion, were studied by XPS analysis .The results showed that the main organic sulfur occurrences in the coal sam-ples are mercaptan (ether), thiophene, (sulfoxide), and organic sulfur occurrences do not change with the coal density changes , and the relative content of thiophene sulfur increases or reduces with the coal density changes , total organic sulfur of the other two kinds increases with the coal density rise .
