Geopolymer-composites with thermomechanical stability as oxygen carriers for fluidized bed chemical looping combustion with oxygen uncoupling

Oxygen carriers based on geopolymer composites with enhanced thermal and mechanical stability have been synthesized and been proposed for chemical looping combustion with oxygen uncoupling. Geopolymer synthesis belongs to green chemistry and ensures chemical and mechanical properties similar to those of high temperature sintering. Suitable metal oxides, such as combinations of Cu, Mn and Fe oxides, have been used as active fillers in geopolymer...
