Cu-ZnO-Al2O3 catalyst modify with light rare earth elements for CO2 hydrogenation to methanol
研究了轻稀土元素La,Ce,Pr,Nd对Cu-ZnO-Al2O3(CZA)催化剂的改性以及改性前后的催化剂在CO2加氢制甲醇反应中的催化性能,比较了Ce/CZA和CZA催化剂上反应温度对甲醇收率的影响,并考察了Ce/CZA催化剂的稳定性;采用XRD、XPS、H2-TPD、CO2-TPD、N2O化学吸附、低温N2吸附-脱附、SEM-EDS等方法表征了催化剂的构效关系.实验结果表明,轻稀土元素改性能提高CZA催化剂的催化性能,Ce改性的效果最好,与C…查看全部>>
The performances of Cu-ZnO-Al2O3(CZA) catalysts modified with light rare earth elements,namely La,Ce,Pr and Nd,in the hydrogenation of CO2 to methanol were investigated. The effects of reaction temperature on the methanol yield over the Ce-modified CZA(Ce/CZA) and CZA catalysts,and the stability of the Ce/CZA catalyst in the hydrogenation were researched. The relationship between the performances and structure of the catalysts were analyzed by means of XRD, …查看全部>>
