Iron oxide - Wikipedia

Methanogenesis replacement by iron oxide reduction. Under conditions favoring iron reduction, the process of iron oxide reduction can replace at least 80% of methane production occurring by methanogenesis. This phenomenon occurs in a nitrogen-containing (N 2) environment with low sulfate concentrations.

Hydrogen production by steamiron process - ScienceDirect

It is a cyclic process for water cleavage, whereby coal is consumed. Coal is gassified to a lean reducing gas, containing carbon monoxide and hydrogen. This gas reacts with iron oxides (haematite Fe 2 O 3, magnetite Fe 3 O 4, wuestite FeO) to produce a reduced form of iron oxide (wuestite FeO, iron Fe). The reduced iron oxide is re-oxidised
