| 摘 要： | 在单层塔板泡沫吸收塔中的ＳＯ２液相催化氧化进行了扩在试验研究，当ＳＯ２净化效率（单板效率）为５０％时，得到１６％（Ｗｔ）Ｈ２ＳＯ４，硫酸生成速率为１８％／ｈ，ＳＯ２吸收最佳敢化５Ｌ／Ｎｍ＾３，添加表面活性剂Ａｌ２（ＳＯ４）３及鼓氧操作对ＳＯ２液相催化氧化有明显促进作用，冶炼烟气ＳＯ２浓度波动吸收效率影响不大。

| Abstract: | Additional experiments of catalytic oxidation of SO2 in aqueous solution have been carried out at a smelting plant in a foamtower containing one serve-plate, 16%(wt)H2SO4 has been obtained while the absorption efficiency of SO2 is above 50%. Producing rate of H2SO4 is about 1.8%(wt)/h. The best ratio of solution and gases is 5L/Nm3. Addition of Al2(SO4)3 and O2 in the solution improves the absorption process. The change of SO2 concentration has small effect on the absorption efficiency. |
