Abstract

The invention is directed to a process to prepare elemental iron by contacting an iron ore feed with a reducing gas to obtain iron and an off-gas. The reducing gas is prepared by performing the following steps (a) partially oxidizing a mixture consisting of a sulphur containing solid carbonaceous fuel and gaseous CO2 as carrier medium with oxygen, by supplying an oxygen containing gas and the solid carbonaceous fuel to a burner, thereby obtaining a gas comprising H2, CO, CO2 and H2S; (b) removing CO2 and H2S from the gas obtained in step (a) to obtain the reducing gas comprising H2 and CO and a first stream comprising CO2 and H2S; (c) reducing the content of H2S in the first stream comprising CO2 and H2S obtained in step (b) in a liquid redox type process and (d) recycling at least part of the CO2 obtained in step (c) to step (a).
