| 摘 要： | 对来自全国26个省、市、自治区的290个煤样中有机硫的质量分数测试及研究,发现煤中有机硫质量分数基本分布在0%1.0%范围内。在低硫煤中硫分以有机硫为主,在高硫煤中以无机硫为主。中、高硫煤中,广西、湖南等地区很大一部分煤中硫分以有机硫为主。在所采集的样品中,高有机硫煤(有机硫>1%)均分布在华南、华北两大聚煤区,属于石炭、二叠纪煤。高有机硫煤中有机硫质量分数的变化与变质程度无明显关系。煤炭形成过程中海水作用的影响,是导致煤中有机硫含量偏高的最主要原因。

| Abstract: | Two hundred and ninety coal samples taken from twenty-six provinces are tested and analysed for their organic sulphur contents.The test results indicated that:the main range of organic sulphur quality fraction in Chinese coals is about 0~1.0%;the organic sulfur is dominant in the coals which characterized by low total sulfur contents,but the inorganic sulfur is dominating in the coals with high total sulfur contents;in Guangxi Province,Hunan Province etc,the organic sulfur is primary in coals which with moderate and high sulfur contents.In all of tested samples,the coals with high organic sulfur contents are distributed in two big coal-cumulating areas:the southern China and northern China,where the coal are mostly Carboniferous and Permian coals.The organic sulfur contents are irrelevant with coal ranks.The coals with high organic sulfur contents are caused by the seawater influence during the coal-generation time. |
