摘要/Abstract

摘要：

考察了乙酸乙酯催化燃烧时,铈锆固溶体中掺杂M (M = Mn, Y)对催化剂MnO_x/Ce_0.50-zZr_0.50-zM_2zO_y/Al₂O₃活性的影响。结果表明: Mn的掺杂明显增加了储氧材料的储氧量(OSC),Y的掺杂明显降低了催化剂的还原温度；Mn 和Y的同时掺杂兼具Mn掺杂和Y掺杂的优点。催化剂MnO_x/Ce_0.40Zr_0.40Mn_0.10Y_0.10O_y/Al₂O₃ 性能最佳,完全转化温度为513K,且T_10% 和 T_100%间隔的温度范围最窄,可适用于较大初始浓度变化范围和较高空速(GHSV)条件下的乙酸乙酯净化。H₂程序升温还原(H₂-TPR)和X射线衍射(XRD)测试显示,MnO_x/Ce_0.40Zr_0.40Mn_0.10Y_0.10O_y/Al₂O₃具有较低的还原温度和较大的还原峰面积； Mn 和Y进入铈锆固溶体的晶格,改善了其织构性能,促进了锰氧化物在载体表面的分散。

Abstract:

The effect of doping M (M = Mn,Y) into ceria-zirconia solid solutions on the activity of MnO_x/Ce_0.50-zZr_0.50-zM_2zO_y/Al₂O₃ for catalytic combustion of ethyl acetate has been investigated. It is found that doping of Mn increases greatly the oxygen storage capacity (OSC) of the oxygen-storage materials (OSMs); doping of Y decreases obviously the reduction temperature of catalysts; the doping of Mn and Y combines the advantages of doping of Mn and Y. MnO_x/Ce_0.40Zr_0.40Mn_0.10Y_0.10O_y/ Al₂O₃ has the best catalytic performance. The complete conversion temperature of ethyl acetate over the catalyst is 513K and the temperature range between T_10% and T_100% is the smallest. This catalyst can be applied to abatement of ethyl acetate under conditions of wider range of inert concentration and higher gas hourly space velocity (GHSV). Results of H₂-temperature-programmed reduction(H₂-TPR)and X-ray diffraction (XRD) analyses show that MnO_x/Ce_0.40Zr_0.40Mn_0.10Y_0.10O_y/Al₂O₃ has lower reduction temperature and larger peak area. Mn and Y enter the lattice of ceria-zirconia solid solutions, which improves the textural properties and greatly promotes the MnO_x dispersion on the support surface.
