| 摘 要： | 为寻求价廉、高效的烟气治理技术；对Ｍｎ＾２＋催化氧化脱除烟气中ＳＯ２的机理及工艺进行了研究。由实验得出其最佳的ｐＨ值为５－６，Ｍｎ＾２＋浓度为０．０６－０．１３ｍｏｌ／Ｌ。采用石灰石中和生成的Ｈ２ＳＯ４可维持较高的吸收率，并副产石膏。与传统的石灰法相比，该法可避免结垢与堵塞，且无需副产石膏所需的氧化过程，从而降低了投资和运行费用。

| Abstract: | n order to develop a low Price and highly efficent Process, the mechanisms and processes for removal of SO2 from flue gas by Mn2+ catalytic oxidation have been studied. The resuhs shaw that the optimum conditions Tor the processes are pH 5-6 and the Mn2+ concentration of 0. 06-0. 13 mol/L. The use of limestone to neutralize H2SO4 in the absorbing solution may keep a high absorbing efficency and prdduce the by-product gypsum. In comparison with traditional limestone method, it may avoid scaling on the walls of equipment and slugging, and may not need a oxidation process for producing gypsum. For these reasons, there is a low investment in equipment and a low operation cost. |
