Zusammenfassung:	The present application relates to the technical field of chemical production, and particularly relates to a molten iron catalyst for high-temperature Fischer-Tropsch synthesis, a preparation method of the molten iron catalyst and an application of the molten iron catalyst in preparation of high-carbon α-olefin from synthesis gas. The molten iron catalyst comprises iron oxides and a cocatalyst, and mass contents of components are: potassium oxide per 0.1-1 g/100gFe; strontium oxide 0.1-1 g/100gFe; manganese oxide 1-20 g/100gFe, and rare earth metal oxides 1-10 g/100gFe; the rest is iron oxides. The molar ratio of ferric iron to double ferrous iron in the iron oxides, namely Fe3+/2Fe2+, is 0.4-1.5. The application aims to provide a molten iron catalyst with high strength, high activity, and high selectivity of higher α-olefin.
