Abstract: PURPOSE:To reduce the content of an iron component in a catalyst and eliminate the need for treating the whole amount of coal, by liquefying a coal by hydrogenation in the presence of a specific supported iron sulfide colloid catalyst. CONSTITUTION:A sulfate or chloride of iron (II) or iron (III) and a sulfide of an alkali metal, such as Na2S, are mixed in a molar ratio of 4-1 in water to obtain an iron sulfide hydrogel having an iron concentration of 5mmol/l or less. 5-20-fold amount of an inorganic compound which is slightly soluble ion water (e.g. CaCO3) is added to and contacted with the hydrogel at 0-60 deg.C to support the iron sulfate colloid on the inorganic compound. The product is dried at 40-100 deg.C in vacuo to obtain a supported iron sulfate colloid catalyst. 98-80wt% coal is mixed with 2-20wt% catalyst an liquefied by hydrogenation at 350-500 deg.C for 30-90min under a hydrogen pressure of 150-300kg/cm .
