1. through contacting the method that MOX is reduced into metallization material with the reducing gas of heat, wherein this reducing gas at least part mixture of material below CR produce:

  • -contain carbonic acid gas (CO 2) and/or water vapour (H 2O) gas and -hydrocarbon gas,The required heat of the heat absorptivity reforming method that wherein in reforming process, takes place part at least is that burning through combustion gases provides, and discharges the combustion exhaust in this generation,Wherein these combustion gases at least partly are being reduced into MOX the top gas acquisition that is produced in the process of metallization material by what part was measured,The top gas that is characterised in that the said part amount that is used to obtain said combustion gases at first carries out dedusting and carries out the CO conversion reaction then, and the reformed gas that in this CO conversion reaction process, is obtained is carried out CO after cooling 2Remove, and will be at the poor CO of this generation 2Reformed gas at least as the component of said combustion gases.
