Abstract
A process to prepare elemental iron by contacting an iron ore feed with a reducing gas at a pressure of between 1 and 10 bar to obtain iron and an off-gas includes preparing the reducing gas by performing the following steps: (a) partially oxidizing a mixture comprising a solid or liquid carbonaceous fuel and oxygen at a pressure of between 10 and 80 bar, thereby obtaining a gas comprising Hand CO; (b) removing COand HS from the gas obtained in step (a) to obtain an intermediate gas comprising Hand CO; (c) supplying the intermediate gas obtained in step (b) to a H-selective membrane to obtain a H-rich permeate gas and a CO-rich retentate; and (d) heating H-rich permeate to obtain a heated H-rich permeate as the reducing gas.
