A model for reduction of FeO with hydrogen in a countercurrent moving bed reactor is summarized. This model is a special case of a mor ecomplete model which also includes reduction of the higher oxides, hematite and magnetite, with a mixture of reducing gases, thus describing the production of direct-reduced iron from iron ores. Equations governing the heat and mass transfer between the gas and solid phase are not given here, but play an important role in the dynamic bahviour of the model.
