  • Hydrogen production by steamiron process ScienceDirect

    The process operates two stages during the reduction step the iron ores are reduced by synthesis or biomass gas, which is thereby oxidised to a lean gas with low remaining CO (68%) and H 2 (ca. 6%) content. In the subsequent oxidation step, the iron ore is re oxidised by water vapour yielding an hydrogen rich fuel gas.

  • Coal based Direct Reduction Rotary Kiln Process IspatGuru

    The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the non coking coal. As the iron ore is in direct contact with the reducing agent throughout the reduction process, it is often termed as direct reduced iron (DRI).

    Sponge iron is not useful by itself, but can be processed to create wrought iron or steel. The sponge is removed from the furnace, called a bloomery, and repeatedly beaten with heavy hammers and folded over to remove the slag, oxidise any carbon or carbide and weldthe iron together. This treatment usually creates wrought iron with about three percent slag and a fraction of a percent of other impurities. Further treatment may add controlled amounts of carbon, allowing various kinds of heat treatment (e.g. quot;steelin
