Abstract

A process for producing direct reduced iron (DRI) from iron ores and reducing the cost and energy requirements of steelmaking utilizing a gas produced from fossil fuels containing sulfur compounds and BTX wherein said gas is heated in a gas heater wherein heat is transferred from a previously heated solid material to the gas. The hot gas is caused to flow through a bed of DRI particles iron oxides or equivalent material outside of the reduction reactor where said material adsorbs sulfur compounds and destroying the BTX. The gas resulting from this treatment free from sulfur compounds and BTX is combined with a reducing gas stream withdrawn from the reduction reactor after H20 and C02 have at least partially been removed for regenerating its reducing potential with or without undergoing a previous cleaning treatment.
