用ＴＰＲ，Ｍｏｓｓｂａｕｅｒ谱法，ＸＰＳ，ＸＲＤ及反应评价等手段研究了Ｆｅ２Ｏ３／ＺｒＯ２催化剂的还原行为、铁物种状态和ＣＯ加氢反应性能．结果表明，预处理条件明显影响Ｆｅ２Ｏ３／ＺｒＯ２催化剂表面铁原子的数量、铁锆间的相互作用、催化剂的物相变化以及ＣＯ加氢反应的催化性能．以Ｆｅ２Ｏ３／ＺｒＯ２经氢氟混合气程序升温至７５３Ｋ还原生成的Ｆｅ－Ｚｒ－Ｏ物种为前身，在合成气中进一步还原得到的铁锆催化剂，具有较好的Ｆ－Ｔ反应合成低碳烯烃的选择性． The reduction behavior, iron species status and CO hydrogenation performance of Fe2O3 / ZrO2 catalysts were investigated by TPR, Mossbauer spectroscopy, XPS, XRD and reaction evaluation. The results show that the pretreatment conditions significantly affect the number of Fe atoms on the surface of Fe2O3 / ZrO2 catalyst, the interaction between Fe and Zr, the phase change of catalyst and the catalytic performance of CO hydrogenation reaction. The Fe-Zr-O species, which was formed by the reduction of Fe2O3 / ZrO2 to 753K by hydrofluorine gas mixture, was used as the precursor to further reduce the obtained Fe-Zr-O catalyst in syngas and had better F-T reaction for the synthesis of light olefins Selective.
