用浸渍法制得一系列不同铁负载量的Ｆｅ２Ｏ３／ＺｒＯ２催化剂，应用催化反应评价结合穆斯堡尔谱对催化剂的ＣＯ加氢反应性能、催化剂活性相结构及催化剂铁物种在合成气反应过程中的物相变化进行了研究．结果表明，铁负载量的大小对于Ｆｅ２Ｏ３／ＺｒＯ２催化剂的Ｆ－Ｔ反应催化性能有很大影响，铁负载量适当时，Ｆｅ２Ｏ３／ＺｒＯ２催化剂铁锆间适当的强相互作用使得催化剂在保持较高催化活性的同时高选择性地生成低碳烯烃，产物分布偏离Ｓｃｈｕｌｚ－Ｆｌｏｒｙ分布规律．
A series of Fe2O3 / ZrO2 catalysts with different iron loadings were prepared by impregnation method. The catalytic hydrogenation of CO coupled with Mossbauer spectroscopy on the catalyst, the active phase structure of the catalyst and the reaction of the catalytic iron species in the synthesis gas were evaluated Phase changes were studied. The results show that the amount of iron loading has great influence on the catalytic performance of F-T reaction of Fe2O3 / ZrO2 catalyst. Appropriate strong interaction between the Fe2O3 / ZrO2 catalyst iron-zirconium when the iron loading is appropriate, Active and high selectivity to produce light olefins, the product distribution deviates Schulz-Flory distribution.
