摘要
研究了采用高温炭化方法以煤为原料制备脱硫剂的方法及其性质。对脱硫剂的饱和吸附量及比表面积进行了测定。７００℃为最适宜炭化温度，讨论了硝酸盐种类及浸渍时间对脱硫剂性能的影响。
A method for manufacture and the properties of desulfurizing substance from coal using high temperature carbonization were studied.The saturation absorptive capacity and the specific surface area of desulfurizing substance were investigated.The optimum temperature of carbonization was 700℃.The effect of different kinds of nitrates and impregnating time on properties of desulfurizer was discussed.
