| 中文摘要 | influences of cao-al2o3 interaction on catalyst coke resistance were studied by adjusting calcination temperatures. the catalyst calcined at 600 °c exhibits the worst, while the one calcined at 800 °c shows the best coke resistance among the catalysts calcined at different temperatures. high activity (86 %) and high stability for cyclohexane dehydrogenation during 220 h investigation are obtained. this is attributed to strong ca-al interaction and relatively large cao particles, which lead to more dispersed pt and larger amount of spilt-over h2. models of ca-al interactions are established, exhibiting the variations of cao particles and the formation of calcium aluminates. |
