采用共浸渍法制备了20CuO-CeO2/Cord.整体式催化剂,分别考察铜铈比为1:9、2:8、3:7、4:6、5:5对催化剂性能的影响.利用气相色谱仪对催化剂的性能进行了测试,并运用程序升温还原技术(TPR)对样品进行了表征.结果表明采用铜铈比为1:9制得的催化剂表现出较好的活性和选择性.
20 CuO-CeO2/Cord. catalysts were prepared by co-impregnation method. The influence of the CuO-to-CeO2 ratio of 1:9 ,2:8 ,3:7 ,4:6 and 5:5 were investigated. Performance of the catalysts were studied by gas chromatograph,the samples were also characterized by means of temperature programmed reduction( TPR) tech-niques. The results showed that catalysts which were made by CuO-to-CeO2 ratio of 1:9 presented good activity and selectivity.
