摘要	Chemical looping partial oxidation of methane (CLPOM) coupled with carbon dioxide splitting process was proposed in this work to achieve high H-2/CO ratio syngas and CO production simultaneously. Manganese ferrite (MnFe2O4) oxygen carrier with a spinel structure was prepared by using a co-precipitation phase inversion method for this methane-carbon dioxide reaction system. The reaction performance of oxygen carrier was investigated in fixed bed reactor combined with the analytical methods of XRD, TPR, H-2-TG and XPS. The results revel that spinel structure MnFe2O4 was successfully prepared and Fe is the main active spices to release lattice oxygen. TG analysis confirms that 43.3% of lattice oxygen can release from MnFe2O4 in H2 atmosphere with highest release rate 0.4%/min at 721 degrees C. The maximum conversion of CH4 and CO2 are 63% and 99% achieved in CLPOM coupled with CO2 splitting process and temperature makes a positive effect on the reaction process. Moreover, the reaction stability of MnFe2O4 oxygen carrier are verified in 10 cycles reaction of CLPOM coupled with CO 2 splitting with the reaction path MnFe2O4 ->(FeO)(0.298)-(MnO)(0.202)/FeO -> MnFe2O4. Moreover, The MnFe2O4 oxygen carriers with different reduction stages were analyzed by XPS to reveal lattice oxygen migration mechanism, which indicates that the bulk lattice oxygen of oxygen carrier gradually dissociated and migrated to the outer surface in reaction process where reacts directly with methane or converts to oxygen adsorption OIL The valence of Mn has not changed in the whole reaction process, whereas, Mn species forms the synergistic effect with Fe to improve the conversion of CH4 and CO2, promoting the oxidization of Fe2+ to Fe3+ in CO2 atmosphere. MnFe2O4 oxygen carrier is a promising candidate for the CLPOM coupled with CO2 splitting process. (C) 2020 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
