Sponge iron reaction - Wikipedia

The sponge iron reaction (SIR) is a chemical process based on redox cycling of an iron-based contact mass, the first cycle is a conversion step between iron metal (Fe) and wuestite (FeO), the second cycle is a conversion step between wuestite (FeO) and magnetite (Fe 3 O 4). In application, the SIT is used in the reformer sponge iron cycle (RESC) in combination with a steam reforming unit.
