铜川煤双氧水氧化脱硫的研究

Study on Desulfurization of Tongchuan Coal with Hydrogen Peroxide

煤的脱硫对其洁净利用非常重要。用双氧水对铜川煤中硫进行脱除,重点考察了温度的影响。结果表明:双氧水用于脱除铜川煤中的硫效果良好,同时对原煤的主体结构影响较小;不同温度下脱硫煤的发热量与原煤相差不大;同时脱硫煤的热稳定性较原煤有所提高。用双氧水脱除铜川煤中的硫时,温度不易超过40℃,最佳温度为35℃。

Desulfurization of coal is very important for its clean utilization.Desulfurization of Tongchuan coal with hydrogen peroxidewas studied,and the influence of temperature was investigated.The results showed that the effect of hydrogen peroxide on sulfur removal in Tongchuan coal is good,and has little effect on the main structure of raw coal.At different temperatures,the calorific value of the desulfurization coal is not quite different from the raw coal.At the same time,the stability of desulfurization coal is improved compared with the raw coal.When sulfur is removed from Tongchuan coal by hydrogen peroxide,the temperature is not easy to exceed 40℃and the optimum temperature is 35℃.
