A novel process for stationary hydrogen production The
The sponge iron reaction process is a cyclic process for water splitting, whereby a syngas is consumed. The syngas reacts with iron oxide (magnetite, Fe3O4) to produce a reduced form of iron oxide (wuestite or iron). The reduced iron oxide is re oxidised with steam to form magnetite and hydrogen.

Characteristics of reduced iron. The MIDREX process produces direct reduced iron (hereinafter referred to as DRI ). The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a
Steam reforming. Steam reforming is a method for producing hydrogen, carbon monoxide, or other useful products from hydrocarbon fuels such as natural gas. This is achieved in a processing device called a reformer which reacts steam at high temperature with the fossil fuel. The steam methane reformer is widely used in industry to make hydrogen.
The Development of New Iron Making Processes
Currently, constructions of new iron reduction plants are being planned or commenced because of the global increase of demand for steel (Figure 2) and increase of reduced iron market price (Figure 3), which is caused by the demand increase, especially in China.

Sponge iron reaction
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.
