摘　　要：费托合成是合成气转化为清洁液体燃料和高附加值化学品的最佳途径和发展方向。铁基催化剂在费托合成反应中应用广泛。研究表明,碳化铁是Fe基费托合成催化剂的活性相,近年来,制备碳化铁直接用于费托合成已成为Fe基费托合成催化剂研究的热点。本工作概述了碳化铁的物相类型,综述了碳化铁的制备方法(主要包括湿化学合成法、热处理渗碳法、铁基金属有机骨架材料热解法、溶胶凝胶法)及其在费托合成中的应用,并对碳化铁在费托合成中的应用前景和研究方向进行了展望。Fischer-Tropsch synthesis is the best way and development direction for the conversion of syngas into clean liquid fuels and high value-added chemicals.Iron-based catalysts are widely used in Fischer-Tropsch synthesis reactions.Studies have shown that iron carbide is the active phase of iron-based Fischer-Tropsch synthesis catalysts.In recent years,the preparation of iron carbide for Fischer-Tropsch synthesis directly has become a hot research topic of iron-based Fischer-Tropsch synthesis catalysts.In this paper,the phase types of iron carbide are summarized,the preparation methods of iron carbide(mainly including wet chemical synthesis,heat treatment carburizing,iron-based organic framework material pyrolysis,sol-gel method) and its application in Fischer-Tropsch synthesis are reviewed,and the application prospect and research direction of iron carbide in Fischer-Tropsch synthesis are prospected.
