| 摘 要： | 以含羧酸配体的钴羰基簇合物Co2（CO）6HCCCOOH，Co3（CO）9CCH2COOH，Co4（CO）10HCCCOOH 为前驱体，γ-Al2O3为载体，通过浸渍法制备了一系列催化剂；同时以Co（NO3）2作为前驱体制备了参比催化剂. 对制备的催化剂进行了费托反应性能评价，并用透射电子显微镜、氨程序升温脱附和傅里叶变换红外光谱等手段对催化剂进行了表征. 结果发现，不同前驱体制备的催化剂对载体上Co的分布具有明显影响，进而影响催化剂活性. 反应结果表明，不同前驱体制备的催化剂上CO转化率及C5+选择性顺序为Co3（CO）9CCH2COOH > Co2（CO）6HCCCOOH > Co4（CO）10HCCCOOH > Co（NO3）2. |

| Abstract: | Co catalysts supported on γ-Al2O3 were prepared using Co2(CO)6HCCCOOH, Co3(CO)9CCH2COOH, and Co4(CO)10HCCCOOH as precursors. Co(NO3)2 was used as the precursor for preparing the reference catalyst. The results of Fischer-Tropsch synthesis tests and characterization by transmission electron microscopy, NH3 temperature-programmed desorption, and infrared showed that the different precursors have significant effects on the dispersion of the Co, which affect their catalytic behavior. CO conversion and C5+ selectivity over these catalysts prepared from different precursors decreased in the order Co3(CO)9CCH2COOH > Co2(CO)6HCCCOOH > Co4(CO)10HCCCOOH > Co(NO3)2. |
