    摘要
  • 摘要: 考察了铁、锡助剂对蜂窝状活性炭担载MnOx-CeO2(MnOx-CeO2/ACH)催化剂的低温脱硝活性及抗硫性能的影响.结果表明,添加FeOx助剂,有利于改善MnOx和CeO2在ACH载体表面的分散性,使得催化剂的脱硝活性在80~200 ℃随反应温度的升高而增加,且抗SO2毒化性能提高;SnOx助剂的添加,使得催化剂在较高温区仍具有较高脱硝活性,并表现出良好的抗SO2毒化性能,在250 ℃时NO转化率由无SO2条件下的98.6%略降至SO2存在时(700 min)的87.8%.
    Abstract: The effect of FeOx and SnOx additives on the catalytic performance of MnOx-CeO2 supported on activated carbon honeycomb (MnOx-CeO2/ACH) in NO removal at low temperature was investigated. The results indicated that the addition of FeOx can improve the distribution of manganese and cerium oxides on the ACH support and enhance the resistance to SO2 poisoning in NO removal; the activity of FeOx-modified MnOx-CeO2/ACH increases with the increasing reaction temperature from 80 ℃ to 200 ℃. Meanwhile, the MnOx-CeO2/ACH catalyst modified with SnOx exhibits high NO removal activity and good resistance to SO2 poisoning at relatively high temperatures; over SnOx-modified MnOx-CeO2/ACH at 250 ℃, NO conversion decreases slightly from 98.6% in the absence of SO2 to 87.8% in 700 min upon the introduction of SO2 in the feed.
