| 英文摘要 | 15co(x)li/ac catalysts promoted by different trace amounts of li doping were prepared by incipient-wetness impregnation. the catalysts were investigated by means of co hydrogenation and characterized by x-ray diffraction (xrd), temperature-programmed reduction (h-2-tpr), and temperature-programmed surface reaction (tpsr) techniques. the results show that co conversion, selectivity towards c5+ hydrocarbons, selectivity towards mixed linear alpha-alcohols and the distribution of higher alcohols (c6+oh) in the alcohol products were improved by adding trace amounts of li to the 15co/ac catalysts. xrd, h-2-tpr, and tpsr results indicate that the existence of trace amounts of li promotes weak interaction between li and co species, disperses the co species of the catalysts, decreases the size of metallic co particles, and promotes the formation of co2c species. |
