Abstract

931,499. Reducing iron ores. ESSO RESEARCH & ENGINEERING CO. Nov. 21, 1961, No. 41599/61. Class 72. A process for the direct reduction of iron oxides in a fluidized bed comprises reducing higher oxides to FeO in an initial stage and reducing FeO to Fe in a final stage, an intermediate exhaust gas containing CO and H 2 and small amounts of C0 2 and H 2 O being removed from the final stage, a minor amount of the intermediate gas being passed to the initial stage and a major proportion being regenerated, added to the gas from a generator zone and fed to the final stage reducing zone. As shown, finelydivided iron oxides in a fluidized bed in vessel 2 are reduced to FeO and removed by a tube 7 for transfer to a final reducing vessel 9 through a line 8. Hot reducing gas is fed to the vessel 9 from a gas generator 10 and a minor part of the exhaust gas is used to reduce the higher oxides in vessel 2. The major part of the exhaust gas is recycled through a line 18 to the gas generator 10. The exhaust gas from vessel 2 may be burned to supply heat to the generator and the products of combustion used to dry or preheat the ore. Any sulphur in the recycled gas may be removed by passing over iron.
