  • Method for reforming reducing gas in a fluidized bed process for reduction of ore
    Patent number: 5912400
    Abstract: A method for reforming reducing gas in a fluidized bed process for reduction of ore in a series of ore reducing reactors, including the steps of: passing ore through a plurality of reducing reactors including a final reactor and at least one upstream reactor; flowing a reducing gas through the final reactor so as to reduce ore in the final reactor whereby a flow of partially spent reducing gas including methane and metallized iron dust exits the final reactor; mixing an oxygen source with the partially spent reducing gas so as to combust a portion of the methane with the oxygen source in the presence of the metallized iron dust and provide a reformed reducing gas; and flowing the reformed reducing gas to the upstream reactor.
