  • Process and plant for the direct reduction of iron-oxide-containing materials
    Patent number: 5871560
    Abstract: A direct reduction process is disclosed for iron oxide-containing materials. Synthesis gas is mixed with top gas produced during direct reduction of the iron oxide-containing materials and is used as reduction gas for directly reducing and heating the iron oxide-containing materials up to reduction temperature. In order to set the H.sub.2 S content at a predetermined value by a relatively simple technique and with a relatively simple equipment, at least part of the sulphur contained in the iron oxide-containing materials as H.sub.2 S produced during heating or direct reduction is added to the reduction gas together with the top gas.
