摘要(Abstract)：

归纳了煤中硫赋存形态,阐述了热解脱硫研究的意义;根据热解过程脱硫方式,将热解脱硫分为不同气氛下热解脱硫和添加物共热解脱硫。不同气氛下热解脱硫方面,分析了惰性、氧化性、还原性3种气氛下热解脱硫效果,结果表明,还原性气氛下脱硫效果最佳,且被脱除的硫多以H2S形态逸出;炼焦煤热解形成焦炭,还原性氢仅与表面含硫化合物反应,脱硫效果有限,因此难以工业化应用。添加物共热解脱硫方面,分析了有机和无机添加物共热解的脱硫效果,结果表明,某些有机和无机添加物与煤共热解时具有脱硫效果,但对于脱除哪类形态硫及各形态硫脱除机理研究甚少;最后提出了热解脱硫技术研究的可能性方向。
Analyze the purpose of study of desulfurization of high-sulfur coal through pyrolysis,summarize the occurrence regularity of sulfurs in coal. The pyrolytic desulfurization technology is basically twofold in nature in accordance with the desulfurization way during pyrolysis. In the research of desulfurization in different atmosphere during pyrolysis,analyze the desulfurization effect in inert atmosphere,oxidizing atmosphere,and reducing atmosphere. The results show that the desulfurization work best in reducing atmosphere,H2S is the main form of sulfur in gas. However,hydrogen can not fully contact with sulfur in the coke during pyrolysis for coking coal,desulfurization is affected,so it can not be scaled up to industrial levels. In the research of desulfurization with additives during pyrolysis,analyze the desulfurization effect which pyrolyze with organic additives and inorganic additives. The results show that some additives work,and there is little research in desulfurization mechanism. Put forward some promising research directions of desulfurization technologies through pyrolysis.
