摘要
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。
Electrolysis desulfurization of Guizhou Liuzhi high sulfur coal is studied in water-methanol, water-ethanol, water-acetone and water-ethylene diamine mixtures using NaOH, HCl, H 2SO 4 and so on as supporting electrolytes. The experimental results indicated that the removal of sulfur from coal is depend on the solvent and electrolyte used and the H 2O-CH 3OH-HCl system is the best one for desulfurization in all kinds of electrolytic system. The removal rate of total sulfur may reach 56% when the electrolysis period is over 3 hours at 50℃in the system. In addition, pure hydrogen gas can be obtained from the cathode cell and its electrolytic current efficiency is about 95%.
