【摘要】 研究了用重金属的硝酸盐浸渍、用以从SO₂/N₂混合气中除去SO₂的脱硫剂的性能,把煤制脱硫剂在1wt％的硝酸盐的水溶液中浸渍,干燥并加热到650℃,浸渍后的脱硫渍对SO₂的吸附容量为常规脱硫剂的2～3倍,讨论了硝酸盐的种类及剂渍时间对脱硫剂性能的影响。更多还原

【Abstract】 The properties of desulfurizer impregnated with nitrates of heavy metals for removal SO2 from a mixture gas of SO2/N2 were studied.The desulfurizer from coal was impregnated in aqueous solution of 1 wt.% nitrate,dried and heated to 650℃.The SO2 adsorption capacity of impregnated desulfurizer was 2 ~ 3 times that of conventional desulfurizer.The effect of nitrales kinds and impregnating time on properties of dcsulfurizer was discussed.更多还原
