摘要
在不同的条件下,考察了不同脱硫剂对煤中全硫和各形态硫的脱硫效果.结果发现,次氯酸钠和双氧水等氧化类脱硫剂对煤中无机硫的脱除效果明显,而甲醇和N,N-二甲基乙醇胺等萃取类脱硫剂对煤中有机硫的脱除效果较好;此两类脱硫剂具有协同效应,配合使用可以增强煤中硫的脱除效果;另外,超声波和微波的辐照作用可以增强有机硫的脱除效率.
In this paper, the desulfurization effect of various desulfurizer in coal washing process was investigated. The removal of total sulfur and various forms of sulfur in coal under different desulfurizer and experimental condition was researched. The results show that the effect of sodium hypoehlorite and hydrogen peroxide as oxidant removing inorganic sulfur in coal is very effective, and that methanol and N,N-dimethylethanolamine as extraction agent could remove effectively organic sulfur in coal. The oxidation desulfurizer and the extraction desulfurizer have cooperative effect, so the combination of the both could increase the desulfurization effect of total sulfur in coal. In addition, the irradiation of microwave and ultrasound could improve the desulfurization efficiency of organic sulfur in coal.
