  • Method of and apparatus for reducing iron oxide to metallic iron
    Patent number: 4880459
    Abstract: This invention relates to a method and apparatus for reducing iron oxide to metallic iron, utilizing a continuous process employing a reducing gas with high hydrogen and carbon monoxide content made by a catalytically reforming mixture of hydrocarbons, reacted off-gases from the reduction process and steam generated from waste heat from the process and or flue gases. Carbon dioxide and water vapor present in the reacted off-gas is utilized as a hydrocarbon reforming oxidant. Steam generated from waste heat from process and/or waste flue gas is also used as a hydrocarbon reforming oxidant. The steam injected into the process gas stream is also used to control the hydrogen-carbon monoxide ratio required for efficient reduction of iron oxide to metallic iron.
