Abstract: A method for manufacturing direct reduced iron wherein iron ore is reduced in a direct reduction furnace by a reducing gas, the reducing gas exiting the furnace through the top as a top reduction gas. The top reduction gas is captured and at least partly subjected to a CO2 recovery step during which it is divided into two streams, a CO2-rich stream and a CO2-poor stream. The CO2-rich stream is subjected to an alkanol production step to produce an alkanol product.
