Chemical Looping Combustion (CLC) of two Victorian brown coals - Part 2: Assessment of interaction between CuO and minerals inherent in coals during multi cycle experiments

► Interaction of mineral matter and CuO during CLC of two Victorian brown coals studied. ► CuO, if used, has to be limited to around 800 °C. ► No deposition of carbon on the CuO. ► Mass loss of CuO due to mineral interaction 0.3-2%/cycle.
