摘要 采用共沉淀法制备Ti1-xSnxO2复合氧化物,浸渍负载质量分数10%的CuOx和FeOy活性组分,制备一系列Cum-Fen/Ti1-xSnxO2催化剂。探究不同Ti/Sn和Cu/Fe(物质的量比)对Cum-Fen/Ti1-xSnxO2催化剂的NH3-SCR反应活性的影响。研究结果表明,Ti0.67Sn0.33O2载体可促进活性组分CuOx和FeOy的相互作用。当Cu/Fe为3∶1时,在300 ℃ 下NOx的转化率达到91.3%;向反应体系通入286 mg/m3 SO2反应3 h后,NOx的转化率仅下降2.6%。X射线光电子能谱(XPS)、程序升温还原(H2-TPR)、程序升温脱附(NH3-TPD和NOx-TPD)的表征表明,CuOx和FeOy之间存在相互作用,与单一的Cu/Ti0.67Sn0.33O2和Fe/Ti0.67Sn0.33O2对比,复合催化剂表面吸附氧浓度相对增加15%~33%,总酸量增大56%,从而提高了催化剂脱硝活性。

关键词:  NH3-SCR  Ti1-xSnxO2复合氧化物  Cum-Fen/Ti0.67Sn0.33O2复合脱硝催化剂  抗硫活性    
Abstract: The Ti1-xSnxO2 composite oxide was prepared by co-precipitation method, and a series of Cum-Fen/Ti1-xSnxO2 catalysts were prepared by impregnating active components of CuOx and FeOy with a mass fraction of 10%. The effect of different n(Ti)∶n(Sn) and n(Cu)∶n(Fe) on the NH3-SCR reaction activity of the catalyst was investigated. The results showed that the Ti0.67Sn0.33O2 composite oxide carrier could promote the interaction between the active components CuOx and FeOy. When n(Cu)∶n(Fe) was 3∶1, the conversion rate of NOx reached 91.3% at 300 ℃. Then after 100 ppm of SO2 was introduced into the reaction system for 3 h, the NOx conversion of Cu3-Fe1/Ti0.67Sn0.33O2 decreased by only 2.6%. X-ray photoelectron spectroscopy (XPS), temperature programmed reduction(H2-TPR) and temperature programmed desorption (NH3-TPD and NOx-TPD) showed that the interaction existed between CuOx and FeOy. Compared with Cu/Ti0.67Sn0.33O2 and Fe/Ti0.67Sn0.33O2, the adsorption oxygen concentration on the surface of the composite catalyst increased by 15%~33%, and the total acid amount increased by 56%, which improved the catalyst activity.
