The steam–iron reaction was examined in a two-compartment fluidized-bed reactor at 800–900 °C and atmospheric pressure. In the fuel reactor compartment, freeze-granulated oxygen carrier particles consisting of Fe3O4 supported on inert MgAl2O4 were reduced to FeO with carbon monoxide or synthesis gas...
