一种铁催化剂、制备方法及其在合成气制备烃类反应中的应用
摘要：
本发明公开了一种铁催化剂，其特征在于该催化剂由30-95重量％铁、0.5-30重量％铝和0-40重量％至少一种选自元素周期表I B、IIB、IIIB、IVB、VIB、VIIB和VIIIB族中的过渡金属M组成，铁主要是以纳米晶粒的金属态存在。该催化剂是采用快速凝固法使熔融的合金以大于1000℃/S以上的冷却速率快速固化获得急冷合金，然后通过碱抽提除去合金中的铝得到。该催化剂用于费托合成反应时，具有比骨架铁高的活性和选择性。
摘要（英）：

The present invention discloses an iron catalyst. It is characterized by that said catalyst is formed from 30-95wt% of iron, 0.5-30wt% of aluminium and 0-40wt% of at least one transition metal M selected from subgroups of IB, IIB, IIIB, IVB, VIB, VIIB and VIIIB of periodic table of chemical elements. The iron is existed by mainly adopting metal state form of nano grains. Said catalyst can be obtained by adopting rapid coagulation process to make molten alloy be quickly solidified according to cooling rate greater than 1000deg.C/S to obtain fast-cooled alloy, then utilizing alkali extraction process to remove aluminium from alloy. When said catalyst is used for making Fischer-Tropsch synthesis reaction, as compared with skeleton iron it possesses high activity and selectivity.
