Abstract (en)
[origin: WO2011012452A1] The present invention relates to a method for reducing metal oxides (3) to metallised material through contact with hot reducing gas, which is produced at least partly by catalytic reforming of a mixture of a gas, containing carbon dioxide (CO2) and/or water vapour (H2O), with gaseous hydrocarbons, wherein the heat for the endothermic reforming processes occurring during the reforming is supplied at least partly by combusting a combustion gas. The present invention further relates to a device for carrying out the method.
