摘　　要：应用扫描电镜、能谱仪和波谱仪测定了煤中有机硫含量。a.在镜质体有机硫含量低于0.50％的煤中,惰质体的有机硫含量与其相近。而在镜质体有机硫含量高于0.5％的煤中,惰质体的有机硫含量大多为镜质体的40％～50％。各种镜质体和惰质体的有机硫含量随其凝胶化程度增高而增加。b.聚煤古地理环境对煤中有机硫含量起决定性作用。以镜质体为例,形成于湖滨三角洲平原环境的神木煤含有机硫0.21％,形成于滨海三角洲平原环境的水城大河边煤含有机硫0.84％,形成于泻湖海湾环境的兖州晚石炭世煤含有机硫2.24％。The SEM,EDS,and WDS are used for the organic sulfur(S_o) determination in coal. 1.In low sulfur coals,while S_o content is less than 0.50%,S_o content of inertinite is similar to that of vitrinite.However,in the coals,whost S_o is more than 0.50%,the S_o of inertinite is mostly 40%～50% of that of vitrinite.S_o content incresses with their gelification degree.Meanwhile, sporinite,cutinite and alginite contain S_o more than vitrinite. 2.The palaeogeographic environment of coal accumulation evidently influence on S_o content in coal.The vitrinite of Shen-Mo coal,which accumulated in lacustrine delta plain,contain 0.21% S_o,the vitrinite in Shui — Cheng coal,which accumulated in coastal delta plain,contain 0.84% S_o,in Yan—Zhou coal,which is borne in paralic,sequence is so high as 2.24%.
