The present disclosure relates to the technical field of Fischer-Tropsch synthesis reaction catalysts, and discloses a supported &#x3b5;/&#x3b5;' iron carbide catalyst for Fischer-Tropsch synthesis reaction, preparation method thereof and Fischer-Tropsch synthesis process, wherein the method comprises the following steps: (1) dipping a catalyst carrier in a ferric salt aqueous solution, drying and roasting the dipped carrier to obtain a catalyst precursor; (2) subjecting the catalyst precursor and Hto a precursor reduction at the temperature of 300-550&#xb0; C.; (3) pretreating the material obtained in the step (2) with Hand CO at the temperature of 90-185&#xb0; C., wherein the molar ratio of H/CO is 1.2-2.8:1; (4) preparing carbide with the material obtained in the step (3), Hand CO at the temperature of 200-300&#xb0; C., wherein the molar ratio of H/CO is 1.0-3.2:1. The preparation method has the advantages of simple and easily obtained raw materials, simple and convenient operation steps, being capable of preparing the catalyst with 100% pure phase &#x3b5;/&#x3b5;&#x2032; iron carbide as the active phase, the catalyst has lower selectivity of COand CHand higher selectivity of effective products.
