采用SiO2作为载体,利用浸渍法负载Cu、Zn和Fe,通过不同的浸渍顺序获得多种CuFe基催化剂,并用固定床反应器测试了这些催化剂的CO加氢反应活性,Cu、Zn和Fe同时浸渍的催化剂活性最高,而分步浸渍导致活性下降。XRD结果说明这是由于共浸渍使得CuFe两种组分相互均匀分布,形成的活性中心最多,反应性能最高。<br/>Adopting SiO2 as carrier, CuFe-based catalysts were prepared through different impregnation se-quences which were impregnated by Cu, Zn and Fe. The activity of CO hydrogenation of these cat-alysts was tested in fixed-bed reactor. The catalyst impregnated by Cu, Zn and Fe simultaneously has the highest activity, but consecutive impregnation leads to the decrease of activity. The results showed that the co-impregnation makes Cu and Fe distribute uniformly in the catalyst, which forms the most active centers, with the highest reactive performance.
