ABSTRACT:
Method and apparatus for the production of prereduced iron ore, Direct Reduced Iron (DRI), or the like, in an ironmaking plant wherein the reducing gas utilized in the chemical reduction of iron oxides is generated from natural gas within the reduction reactor system by reforming the hydrocarbons with such oxidants as water and oxygen inside the reduction reactor which under steady state conditions contains metallic iron which acts as a reformation catalyst. The amount of carbon in the DRI can be reliably controlled by modifyng the relative amounts of water, carbon dioxide and oxygen in the composition of the reducing gas fed to the reduction reactor. The amount of carbon in the DRI is controlled by the amount of water in the reducing gas fed to the reduction reactor while the addition of oxygen provides the energy necessary for such DRI carburization.
