【摘要】 对煤在还原性气氛下热解硫的析出机理的研究进行综述, 着重介绍了在氢气气氛下、焦炉气气氛下的脱硫机理及脱硫效果; 并指出煤在甲烷气氛下热解, 甲烷对脱硫存在促进作用。比较几种还原性气氛下煤热解的脱硫优缺点, 指出甲烷对促进煤热解脱硫具有重要的研究价值和实际应用前景。更多还原

【Abstract】 Progresses of coal desulfurization with pyrolysis in reductive atmosphere were reviewed. The review emphasized on desulfurization mechanism and effect under hydrogen and coke-oven-gas atmosphere. In addition, methane has promoting effect on coal desulfurization. Comparing the advantage and disadvantage of pyrolysis desulfurization in the reductive atmosphere, the methane has an important research value and practical application foreground for promotion the coal pyrolysis desulfurization.更多还原
