    Development of iron ore oxygen carrier modified with ...
    Natural iron ore as oxygen carrier for Chemical looping combustion (CLC) for CO2 capture has attracted increasing attention. However, the major challenge of iron ore is the relatively low reactivity. In this paper, the iron ore was combined with biomass ash to promote its performance. The reduction reactivity of the combined iron ore was determined using CO in TGA and fluidized bed.
