The SCR of NO by propene on coconut shell activated carbon CS(AC) supported with Fe has been undertaken in heated temperature programmed fixed bed vertical column reactor in simulated flue gas atmosphere at 100–550 °C. Catalysts were characterized by N₂ adsorption–desorption, ICP, XRD, TEM, XPS, H₂-TPR, Py-FTIR and NO-TPD. Series of experiments demonstrated that 10 Fe-CS(AC) showed 95% NO reduction at 350 °C. During the tests, different loadings of iron have a significant effect on acid sites, surface area and pore sizes, effects of O_2, SO₂, and H₂O were investigated. The curves of the H₂-TPR shows that there is a strong reduction activity of the catalyst at about 600 °C, which is caused by the strong reduction performance of Fe₂O₃. The analysis of Py-FTIR results defines the presence of Lewis and Brόnsted acids on the surface of the catalyst. At the higher temperature range, the reduction properties of 10 Fe-CS(AC) demonstrated better results than other catalysts.

在加热的程序升温固定床立柱反应器中，在模拟烟气气氛中，在100-550°C的温度下，进行了以Fe为载体的椰壳活性炭CS（AC）上丙烯的一氧化碳氮SCR。催化剂以N ₂吸附-解吸，ICP，XRD，TEM，XPS，H ₂ -TPR，Py-FTIR和NO-TPD为特征。系列实验表明，在350°C下10 Fe-CS（AC）的NO还原量达到95％。在测试过程中，不同的铁负载量对酸位，表面积和孔径有显着影响，研究了O _2， SO ₂和H ₂ O的影响。H ₂的曲线-TPR表明，在约600℃下，催化剂具有很强的还原活性，这是由于Fe ₂ O ₃的强还原性能引起的。对Py-FTIR结果的分析确定了催化剂表面上路易斯酸和布朗斯台德酸的存在。在较高的温度范围内，10 Fe-CS（AC）的还原性能显示出比其他催化剂更好的结果。
