| 英文摘要 | the effect of li promoter on the catalytic performance of the activated carbon (ac) supported cobalt catalysts (co/ac) for co hydrogenation was investigated by means of co hydrogenation, x-ray diffraction (xrd), temperature-programmed reduction (h-2-tpr), and temperature-programmed desorption of adsorbed co (co-tpd). the results showed that the addition of li significantly suppressed the formation of gaseous hydrocarbons and remarkably improved the selectivities for higher hydrocarbons (c5+) and mixed linear alpha-alcohols (c-1-c-18) of co hydrogenation over the co/ac catalyst. however, the activity of co hydrogenation decreased gradually with the increase of li loading in the co-based catalyst. h-2-tpr and co-tpd results illuminated that the existence of li decreased the reducibility of co2+ and the ability of co dissociation, which was the rate-determining step. xrd results indicated that the existence of li promoter enhanced the formation of co2c species. |
