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 monoxide ...
