摘要:
采用浸渍法制备Mn掺杂的Cu-Co整体催化剂,通过X线衍射(XRD)、N2吸附-脱附、扫描电子显微镜(SEM)等手段对催化剂进行表征,并以醋酸甲酯催化燃烧为探针反应,考察涂层中CeO2与Zr0.5Ti0.5质量比、Mn掺杂量、焙烧温度等条件对催化剂性能的影响。结果表明:涂层中CeO2与Zr0.5Ti0.5质量比为2:1,Mn掺杂量为6%,n(Mn):n(Cu):n(Co)为2.2:1:2,焙烧温度为500 ℃时,催化剂具有最佳的活性。当醋酸甲酯质量浓度为9 g/m3,质量空速为12 L/(g·h)时,醋酸甲酯转化率达到90%的反应温度为256 ℃。
Abstract:
A series of Mn doped Cu-Co monolithic catalysts were prepared by a wetness impregnation method.The catalysts were characterized by X-ray diffraction(XRD),N2 adsorption and desorption, and scanning electron microscopy(SEM).The effects of mass ratio of CeO2 and Zr0.5Ti0.5,Mn dosage and calcination temperature on the catalytic performances in catalytic combustion of methyl acetate were investigated.The result showed that when the mass ratio of CeO2 and Zr0.5Ti0.5 was 2:1,Mn dosage was 6%,n(Mn):n(Cu):n(Co)was 2.2:1:2, and the calcination temperature was 500 ℃,thus the catalyst exhibited the best catalytic activity.When the methyl acetate concentration was 9 g/m3 and the weight hourly space velocity(WHSV)was 12 L/(g·h),the reaction temperature was 256 ℃ with methyl acetate conversion of 90%.
