|20140260803||PROCESS FOR PRODUCING DIRECT REDUCED IRON (DRI) UTILIZING GASES DERIVED FROM COAL - A process for producing direct reduced iron (DRI) from iron ores, utilizing a gas produced from fossil fuels, particularly coal, containing sulfur compounds and BTX, wherein said gas is heated in a gas heater, preferably of the regenerative type, wherein heat is transferred from a previously-heated solid material to the gas produced from coal. The hot gas is caused to flow through a bed of DRI particles, iron oxides or other equivalent material, outside of the reduction reactor, where said material adsorbs sulfur compounds and the BTX are destroyed. The gas resulting from this treatment, free from sulfur compounds and BTX, is combined with a reducing gas stream withdrawn from the reduction reactor after H||09-18-2014|
|20130305883||METHOD AND APPARATUS FOR PRODUCING DIRECT REDUCED IRON UTILIZING A SOURCE OF REDUCING GAS COMPRISING HYDROGEN AND CARBON MONOXIDE - The present invention concerns a method and an apparatus for producing DRI (Direct Reduced Iron) utilizing a high-oxidation reducing gas containing carbon monoxide and hydrogen, derived directly or indirectly from the gasification of hydrocarbons or coal, with a high content of oxidants (H||11-21-2013|
|20120125157||METHOD FOR PRODUCING DIRECT REDUCED IRON WITH LIMITED CO2 EMISSIONS - A method and apparatus for producing direct reduced iron (DRI), also known as sponge iron, by means of direct contact of iron oxides with a stream of recycled and regenerated hot reducing gases containing hydrogen and carbon monoxide. The invention provides a way for decreasing the uncontained emission of CO||05-24-2012|
