| 英文摘要 | a series of noble metal (pt, ru or pd) promoted co/al2o3 catalysts were prepared by sequential impregnation method. the catalysts were characterized by xrd, tpr, h-2-tpd and tpsr techniques, and their catalytic performance in fischer-tropsch synthesis was investigated in a fixed-bed reactor. the results of activity measurements show that the addition of small amounts of noble metal greatly improved the activity of the co/al2o3 catalyst. tpr experimental results demonstrate that hydrogen spillover from the noble metal to cobalt oxide clusters facilitated the reduction of cobalt oxide and, thus significantly increased the reducibility of co/al2o3 catalyst. the presence of noble metal increased the amount of chemisorbed hydrogen and weakened the bond strength of co-h. tpsr results indicate that co was adsorbed in a more reactive state on the promoted catalysts. |
