Summary:A process and an installation for reducing particulate material containing iron oxide are shown, wherein the material containing iron oxide is at least partially reduced with reducing gas in a reducing zone and the waste gas produced during the reduction is drawn off and subsequently subjected to CO2 cleaning in a CO2 separating device (1), in which a tail gas containing CO2 is separated. The tail gas is subjected to combustion and subsequent dewatering in a dewatering device (5), the substitute gas thereby formed being used as a substitute for inert gas.
