Claim:
1. A micro-spherical iron-based catalyst for Fischer-Tropsch synthesis in a high temperature slurry bed reactor, the catalyst including Fe element as a main active component, the catalyst comprising: a K promoter, a transitional metal promoter M, and a structure promoter S, wherein the transitional metal promoter M is any combination of two or more kinds of metals selected from the group consisting of Cr, Cu, Mn and Zn; the structure promoter S is selected from the group consisting of SiO2 and Al2O3, wherein the SiO2 and Al2O3 are modified by at least one of MoO3, TiO2 and ZrO2; and the Fe element, K promoter, transitional metal promoter M, and structure promoter S have a respective weight ratio of Fe:M:K:S=100:1-100:6-8:1-80, wherein the Fe element and the transitional metal promoter M are calculated based on metal elements, and the structure promoter S is calculated based on oxides.
