【摘要】 总结了当前煤中硫分的主要存在形态及其在煤转化（包括热解和气化等）过程中硫分变迁规律的研究进展，并探讨了煤阶和煤中硫的赋存形态，以及操作条件对煤中硫分析出规律的影响，这些形成了煤热解部分气化预脱硫工艺的理论基础，这对于指导燃前脱硫工艺的研究与开发是非常重要的．更多还原

【Abstract】 This review is intend to summarize the present state of knowledge on the chemical forms of sulfur in coal, and progress of sulfur behavior during coal conversion process (including pyrolysis and gasification) achieved. The effects of coal rank, forms of sulfur in coal and conditions of operation to sulfur removal were described, which construct the basic of theory for desulfurization. It is important to guide the R & D the economics process of desulfurization of pre-combustion.更多还原
