Summary: | PCT No. PCT/AT95/00121 Sec. 371 Date Jan. 15, 1997 Sec. 102(e) Date Jan. 15, 1997 PCT Filed Jun. 20, 1995 PCT Pub. No. WO96/00302 PCT Pub. Date Jan. 4, 1996A 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 H2S 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 H2S produced during heating or direct reduction is added to the reduction gas together with the top gas. |
