| 摘 要： | 以3种高硫煤为对象，考察了反应温度、反应时间、Fe2(SO4)3溶液浓度和原煤粒度等因素对Fe2(SO4)3溶液热处理脱硫效果的影响，并对脱硫前后原煤理化性质的变化进行了研究。结果表明：在Fe2(SO4)3溶液浓度为1 mol/L，反应温度为90 ℃，反应时间为4 h，煤粒度小于0.096 mm的条件下，原煤中黄铁矿硫的脱除率高达67%，而煤中的有机硫含量并无明显的变化；升高反应温度，增加Fe2(SO4)3溶液浓度，延长反应时间以及减小原煤粒径均可在一定程度上提高原煤的黄铁矿硫和全硫的脱硫率；经Fe2(SO4)3溶液处理后原煤的黏结性均出现了不同程度的下降，其中新峪煤完全失去了黏结性；Fe2(SO4)3溶液脱除原煤中无机硫主要是通过Fe3+的强氧化性将黄铁矿硫氧化为SO2-4进而脱除。
