摘要： A method for reducing iron-oxide-containing feedstocks by introducing a reducing gas into a high-pressure reducing unit (1) where the reducing gas is consumed by reducing iron-oxide-containing feedstocks and then the reducing gas is withdrawn as top gas from the high-pressure reducing unit (1). At least one subportion of the top gas is admixed to a feed gas as recycle gas (15). The reducing gas is generated by CO2 being separated off from the gas mixture obtained from the addition of the recycle gas (15) to the feed gas after one or more compression steps. The recycle gas (15) is added to the feed gas in at least two recycle gas substreams that are separated from one another with recycle gas substream pressures at various distances from the high-pressure reducing unit (1).

摘要： A gas stream containing both hydrocarbon and hydrogen is separated into a hydrogen-rich fraction and a hydrocarbon-rich fraction. Then at least one sub-quantity of the hydrocarbon-rich fraction is subjected to at least one operation from the group oxidation using technically pure oxygen and reforming using CO2 and H2O. The result is introduced at least as a component of a reduction gas into a reduction unit containing the metal oxides. As a result of the at least one operation, the hydrocarbon content in the reduction gas on entry into the reduction unit is below 12% by volume.

摘要： An indurating furnace has a heating station and an air passage leading to the heating station. A draft of preheated recirculation air is driven through the passage toward the heating station, and is mixed with fuel gas to form a combustible mixture of preheated recirculation air and fuel gas that ignites in the passage. This is accomplished by injecting the fuel gas into the passage in a stream that does not form a combustible mixture with the preheated recirculation air before entering the passage.
