| 中文摘要 |
| 为寻求价廉、高效的烟气治理技术,对Mn2+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,Mn2+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。 |
| 英文摘要 |
| In 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. |
