Abstract

PURPOSE: Revolving furnace dust, electric furnace dust, or mill scale, which are obtained in iron mills as by-products, is used as a catalyst to liquefy coal economically utilizing waste products with no use of expensive catalysts.
CONSTITUTION: Revolving furnace dust, electric furnace dust, which are mainly composed of a mixture of Fe3O4 and Fe2O3, and/or mill scale, mainly composed of Fe3O4, are used as a catalyst for coal liquefaction to be mixed with a solvent and coal. Then, the hydrogenolysis under high temperatures and pressures are effected to liquefy the coal. This catalyst is preferably more activated, when it is combined with sulfur or made to react with hydrogen sulfide and used in the form of sulfide.
