Abstract: In this study, siderite ore from Hekimhan (Malatya, Turkey) was calcined and tested as the oxygen carrier (OC) in a laboratory-scale chemical looping combustion (CLC) setup by using CO and H₂ mixtures. Fuel conversion of 92% was obtained as a mean of four tests performed at 850°C. It was determined that calcination of the ore before the tests led to the generation of MnFe₂O₄, a bimetallic OC that includes the synergistic benefits of both metal oxides. It was concluded that siderite is a proper OC for pilot or sub-pilot applications.
