CuO promoted Mn2O3-based materials for solid fuel combustion with inherent CO2 capture

We experimentally demonstrate the promising redox and oxygen release characteristics of a novel bimetallic Cu-Mn oxygen carrier for chemical-looping with oxygen uncoupling (CLOU) based CO2 capture. The new material was prepared via a co-precipitation technique and showed a higher oxygen partial pressure than pure CuO and a higher oxygen carrying capacity than Mn2O3, thus, synergistically combining the advantages of the individual metal oxides. The promising CLOU characteristics of the new material were demonstrated further by combusting charcoal fully in a fluidized bed and producing a pure stream of CO2.
