| 摘 要： | 研究煤中硫的结构、赋存形态对有效脱除煤中硫的影响，节约回收稀缺炼焦煤资源，为建立煤中硫的高效脱除方法提供科学依据，提高煤炭综合利用水平，节约稀缺煤种资源具有重要意义。利用XPS测试方法对汾西高硫炼焦煤中硫的赋存形态进行研究，结果表明，煤中无机硫含量较低，以有机硫为主。有机硫的赋存状态共有3类，含量从高到低依次为硫醇（醚）类、亚砜类、噻吩类。

| Abstract: | Studying sulfur structure in coal and its chemical speciation has important slgmllcance m e~tect~ve re- moval of sulfur from coal, saving and recycling scarce resources of coking coal, providing a scientific basis for ef- ficient removal of sulfur from coal, improving comprehensive utilization level of coal, coal saving scarce re- sources. Sulfur chemical speciation in coking coal of Fenxi was studied with XPS method. The results showed that inorganic sulfur content in coal is small, and organic sulfur content dominates. Three categories of organic sulfur chemical speciation according content order from high to low are thiols （ether）, sulfoxides, thiophenes. |
