| 摘 要： | 采用沉淀-浸渍法制备Co/ZnO催化剂，研究还原温度对Co/ZnO催化剂F-T合成反应性能影响。结果表明，催化剂Co/ZnO适宜在较低温度还原，Co负载质量分数5%和10%的催化剂最佳还原温度分别为260 ℃和250 ℃。还原温度与催化剂活性之间的关系取决于Co/ZnO催化剂上Co的分布状态，氧化态Co以约50 nm的颗粒存在于ZnO表面，容易被氢还原。低温还原的Co基催化剂是浆态床F-T合成的良好催化剂。

| Abstract: | Co/ZnO catalysts were prepared by precipitation-impregnation method.The influence of reduction temperature on catalytic performance of Co/ZnO catalysts for Fischer-Tropsch synthesis was investigated.The results showed that Co/ZnO catalyst for Fischer-Tropsch synthesis was fit to be reduced at low temperature.Compared with the catalysts reduced at high temperature,the catalysts with Co loadings of 5wt% and 10wt% reduced at 260 ℃ and 250 ℃ respectively showed higher CO conversion.The relation between reduction temperature and catalyst activity was decided by cobalt distribution state on Co/ZnO catalyst.Oxidizedcobalt with particle sizes about 50 nm existed on ZnO surface,and was easily reduced by hydrogen.The cobalt-based catalyst reduced at low temperature is a good candidate for slurry-bed Fischer-Tropsch synthesis. |
