以氢氧化钠、盐酸和硫酸等为支持电解质，对贵州六枝高硫煤在水－甲醇、水－乙醇、水－丙酮及水－乙二胺等４种混合溶剂体系中电解脱硫率进行了考察。实验结果表明，煤的脱硫率与溶剂及电解质有关，其中Ｈ２Ｏ－ＣＨ３ＯＨ－ＨＣｌ是最佳的脱硫体系，５０℃时，电解３ｈ后其脱硫率可高达５６％。在阳极电解脱硫的同时，阴极联产高纯氢气，其电流效率高达９５％以上。
Using NaOH, H2SO4 and H2SO4 as supporting electrolytes, the electrolytic desulfurization rate of Guizhou Liuzhi high sulfur coal in four mixed solvent systems of water - methanol, water - ethanol, water - acetone and water - ethylenediamine was studied Inspected Experimental results show that the desulfurization rate of coal is related to solvents and electrolytes. Among them, H2O-CH3OH-HCl is the best desulfurization system, and the desulfurization rate can reach as high as 56% at 50 ℃ for 3h. In the anode electrolytic desulfurization at the same time, cathode co-production of high-purity hydrogen, the current efficiency of up to 95%.
