Method and apparatus for preparing compacts of an iron and carbonized coal having a low sulfur content. Coal and iron oxide or metallic iron are formed into compacts, heated, and contacted within an enclosed reactor with a gas containing elemental hydrogen. Hydrogen sulfide is formed by reaction of the hydrogen with sulfur in the compacts and off-gasses are formed from this reaction and from carbonization of the coal. The hydrogen sulfide is separated from the off gases and a portion of the off gases returned to the enclosed reactor. Desulfurized compacts are discharged from the reactor and contain carbonized coal and iron metal, the compacts being low in sulfur content and especially useful in metallurgical processing.
