PURPOSE:To perform coal liquefaction simply in high activity and in economically advantageous manner, by using as catalyst a product prepared by calcination, under specified conditions in a sulfur oxide gas atmosphere, of ion oxide- contg. powder and carbonaceous matter-contg. powder. CONSTITUTION:The objective coal liquefaction is carried out by using, as catalyst, a product prepared by calcination, pref. using a fluidized bed furnace in a sulfur oxide gas atmosphere containing SO2, SO3, etc. at 600-1,200 (pref. 700-1,000) deg.C, of a mixture of iron oxide-contg. powder (FeO, Fe3O4, Fe2O3 etc.) and carbonaceous matter-contg. powder (coke, activated carbon, graphite, etc.).
