| 摘 要： | 低温选择性催化还原(SCR)技术具有很高的脱硝效率。概述了低温SCR金属氧化物催化剂的制备方法和性能,分析了催化剂的失活原因和再生方法,探讨了催化反应的机理,并介绍了低温SCR技术在工业烟气脱硝中的应用案例。SCR催化剂未来的发展不仅要以低温下的高活性和高选择性为主要目的,还要考虑到催化剂的抗失活性能(如抗硫性和抗水稳定性)和操作温度范围,使其可广泛应用于不同的工况中,以满足我国日益提高的环保要求。

| Abstract: | Low-temperature selective catalytic reduction （SCR） is a most efficient denitrification technology. The preparation methods and properties of metal oxide catalysts for low-temperature SCR are summarized. The deactivation reasons and regeneration methods of the catalysts are analyzed. The mechanisms of the catalytic reaction are explored. And the application cases of low-temperature SCR technology in denitrification of industrial flue gas are introduced. It is pointed out that：Not only the high activity and selectivity at low temperature of SCR catalysts should be the aim for further development,but also the anti-deactivation performance （such as sulfur resistance and water stability resistance） and the operating temperature range,in order to apply SCR catalysts in different operating conditions. |
