Characterization of iron ore with Al2O3 as oxygen carrier in Chemical Looping Combustion (CLC)
Chemical looping combustion (CLC) is one of the carbon capturing technologies, in which oxygen from oxygen carrier reacts with fuel inside fuel reactor to produce CO2 and H2O.

| Summary: | Chemical looping combustion (CLC) is one of the carbon capturing technologies, in which oxygen from oxygen carrier reacts with fuel inside fuel reactor to produce CO2 and H2O. Fe-based oxygen carrier is widely used in CLC due to the low cost and less susceptible to carbon formation. This research focuses on synthesizing and characterizing iron ore with alumina in order to analyse the suitability of Malaysia iron ore as an oxygen carrier for CLC application. Iron ore with alumina was prepared using ball milling at various milling time which are 1 hour, 6 hours, 8 hours and 10 hours. The phase transformation, morphology and elemental composition of obtained samples were characterized using X-Ray Diffraction (XRD), scanning electron microscopy (SEM), and Energy Dispersive X-Ray (XRD), respectively. In CLC application, high reactivity of CLC can be obtained with the small particle size of oxygen carrier. This research succeeded in producing Fe2O3/Al2O3 using ball milling with particle size that less than 10μm with crystallite size 17nm at 10 hours, which favourable to be used as oxygen carrier. © Published under licence by IOP Publishing Ltd. |
