DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

The Sponge Iron Process (SIR) is a well-known technology for the production and purification of hydrogen. It consists of a cyclic process in which a feed gas, rich in carbon monoxide and hydrogen (e.g. syngas), is passed on an iron oxide (magnetite Fe3O4) at high temperature. Magnetite is reduced to wuestite (FeO) or iron while carbon …
