Methane Chemical Looping Partial Oxidation Over NiO/Ce2(SO4)3-MgO Oxygen Carrier to Produce High Purity Syngas
摘要
Partial oxidation of methaneMethane to syngas by chemical looping technologyTechnology is a meaningful processProcess for methaneMethane transformation. Thermodynamic and kineticKinetics analyses both forecast the NiO/Ce2(SO4)3-MgOMgO which is a promising oxygen carrierOxygen carrier (OC) for methaneMethane chemical looping partial oxidationChemical looping partial oxidation (CLPOM), which enables 100% methaneMethane conversion, syngas selectivity, a 2.15 H2/CO ratio, and excellent cyclic performance. Compared with Ce2(SO4)3, the CH4 conversion rate can increase by 73.19% because of the excellent latticeLattices oxygen availability, large specific surface area, and less carbon deposition. The hierarchical pore structureHierarchical pore structure also provides an ideal micro-environment for the reaction. These results provide fundamental information on the reaction mechanism of NiO/Ce2(SO4)3-MgOMgO OC and present it as a promising candidate to produce the high purity syngas.
