Performance and kinetics of iron-based oxygen carriers reduced by carbon monoxide for chemical looping

Xiuning HUA,Wei WANG,Feng WANG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 6,   Pages 1130-1138 doi: 10.1007/s11783-015-0821-y

Abstract: Chemical looping combustion is a promising technology for energy conversion due to its low-carbon, high-efficiency, and environmental-friendly feature. A vital issue for CLC process is the development of oxygen carrier, since it must have sufficient reactivity. The mechanism and kinetics of CO reduction on iron-based oxygen carriers namely pure Fe O and Fe O supported by alumina (Fe O /Al O ) were investigated using thermo-gravimetric analysis. Fe O /Al O showed better reactivity over bare Fe O toward CO reduction. This was well supported by the observed higher rate constant for Fe O /Al O over pure Fe O with respective activation energy of 41.1±2.0 and 33.3±0.8 kJ·mol . The proposed models were compared via statistical approach comprising Akaike information criterion with correction coupled with F-test. The phase-boundary reaction and diffusion control models approximated to 95% confidence level along with scanning electron microscopy results; revealed the promising reduction reactions of pure Fe O and Fe O /Al O . The boosting recital of iron-based oxygen carrier support toward efficient chemical looping combustion could be explained accurately through the present study.

Cooperative effect between copper species and oxygen vacancy in CeZrCuO catalysts for carbon monoxide

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 6,   Pages 1524-1536 doi: 10.1007/s11705-021-2106-2

Abstract: The effects of Zr doping on the existence of Cu and the catalytic performance of Ce0.7−xZrxCu0.3O2 for CO oxidation were investigated. The characterization results showed that all samples have a cubic structure, and a small amount of Zr doping facilitates Cu2+ ions entering the CeO2 lattice, but excessive Zr doping leads to the formation of surface CuO crystals again. Thus, the number of oxygen vacancies caused by the Cu2+ entering the lattice (e.g., Cu2+–□–Ce4+; □: oxygen vacancy), and the amount of reducible copper species caused by CuO crystals, varies with the Zr doping. Catalytic CO oxidation tests indicated that the oxygen vacancy and the reducible copper species were the adsorption and activation sites of O2 and CO, respectively, and the cooperative effects between them accounted for the high CO oxidation activity. Thus, the samples x = 0.1 and 0.3, which possessed the most oxygen vacancy or reducible copper species, showed the best activity for CO oxidation, with full CO conversion obtained at 110 °C. The catalyst is also stable and has good resistance to water during the reaction.
