摘要： A micro-spherical Fe-based catalyst for a slurry bed Fischer-Tropsch synthesis (FTS) comprises Fe as its active component, a transitional metal promoter M, a structure promoter S and a K promoter. The transitional metal promoter M is one or more selected from the group consisting of Mn, Cr and Zn, and the structure promoter S is SiO2 and/or Al2O3. The weight ratio of the catalyst components is Fe: transitional metal promoter: structure promoter: K=100:1-50:1-50:0.5-10. Preparation method of the catalyst comprises: adding the structure promoter S into a mixed solution of Fe/M nitrates, then co-precipitating with ammonia water to produce a slurry, filtering and washing the slurry to produce a filter cake, adding the required amount of the K promoter and water to the filter cake, pulping and spray drying, and roasting to produce the micro-spherical Fe-based catalyst for the slurry bed Fischer-Tropsch synthesis. The catalyst has good abrasion resistance and narrow particle size distribution, furthermore, it has high conversion capability of synthesis gas, good product selectivity and high space time yield, and the catalyst also can be used for the slurry bed Fischer-Tropsch synthesis in a wide temperature range.
