摘要
采用共浸渍法制备了整体式Ce-Fe/ZSM-5催化剂并用于NH3-SCR反应。实验结果表明,所制备的催化剂具有良好的低温起燃性能,当反应空速为30,000h-1时,起燃温度T50为239℃,完全转化温度T90为328℃。同时该催化剂具有良好的抗水热老化能力、抗硫性和空速性能,表明其具有很好的应用前景。
Catalyst Ce-Fe/ZSM-5 was prepared by co-impregnation method and was applied to NH3-SCR reaction. The experimental results showed that the as-prepared monolith catalyst has good low-temperature light-off property, the light-off temperature Tso is at 239℃ and the complete conversion temperature Tgois at 328% when the GHSV is 30,000h-1 , meanwhile, this catalyst has good an- ti-hydrothermal, anti-sulfur property as well as space velocity property,indicating that it has nice application prospecL
