| 摘 要： | 采用浸渍法制备负载型CeO2催化剂,应用XRD、SEM技术对所制催化剂进行物相和形貌分析.在常压连续流动固定床石英反应器上考察其在CO2氧化乙烷制乙烯反应的催化性能,实验结果表明:CeO2/-γA l2O3催化剂对CO2氧化乙烷制乙烯反应具有较好的催化活性.当CeO2负载量为15%时,乙烷的转化率为25.8%,乙烯的选择性和收率分别为95.8%和24.7%.

| Abstract: | A series of CeO_(2) catalysts was prepared by impregnation method.The catalysts were characterized with XRD and SEM techniques.The catalytic performance for oxidative dehydrogenation of ethane was studied in the continuous flowing fixed-bed reactor at room pressure.Experimental results indicated that the CeO_(2)/γ-Al_(2)O_(3) catalyst showed higher catalytic activity.The conversation of ethane was 25.8%,the selectivity and yield of ethylene was 95.8% and 24.7% respectively,when the loading of CeO_(2) was 15%. |
