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.
