    摘要
  • 摘要: 在理想平推流反应器中进行了模拟热解气对模拟烟气中NO、N2O的还原实验研究,考察了反应温度、过剩空气系数λ、热解气中CH4、CO、H2、NH3浓度、烟气中NO、N2O浓度变化对NO、N2O出口浓度的影响。实验结果表明,当模拟热解气仅含其中一种气体时,在反应温度973~1 223 K时热解气中CH4、CO、H2基本不与NO发生反应,当λ小于或等于1.0时可降低N2O浓度0%~30%;热解气中NH3可降低NO 10%~60%,但NH3不与N2O发生反应。
    Abstract: Reduction of NO and N2O with the simulated pyrolysis gas has been experimentally studied in an ideal plug flow reactor. The influences of reaction temperature, excess air number λ, concentrations of CH4, CO, H2, NH3 in the simulated pyrolysis gas, concentrations of NO and N2O in the flue gas on concentration of NO as well N2O and total nitrogen conversion efficiency have been discussed. The results show that CH4, CO and H2 cannot effectively react with NO at 973~1 223 K. About 0~30% of the inlet N2O can be reduced by CH4, CO, or H2 when λ is equal to or less than 1.0. Furthermore, about 10%~60% of the inlet NO can be reduced by NH3, however, no N2O concentration change is found when N2O is mixed with NH3 at 973~1 223 K.
