Abstract

A micro-spherical iron-based catalyst and a preparation method thereof are disclosed. The catalyst contains a potassium promoter, and at least one transitional metal promoter M which is one or more kinds of metals selected from Cr, Cu, Mn and Zn. It also contains a structure promoter S, which is SiOand/or AlO, wherein both of SiOand AlOare modified by MoO, TiOand/or ZrO. The weight ratio of components is Fe:M:K:S=100:3-50:1-8:3-50, in which the metal components are calculated based on metal elements, the structure promoter is calculated based on oxides. The catalyst is prepared by co-precipitation method.
