| Abstract Scope |
Partial oxidation of methane (CH4) to syngas by chemical looping technology is a meaningful process for CH4 transformation. Thermodynamic and kinetic analysis both forecast the 20NiO/30Ce2(SO4)3-50MgO is a promising oxygen carrier (OC) for methane chemical looping partial oxidation (CLPOM). It has an outstanding CH4 conversion rate (X(CH4)), syngas selectivity, appropriate syngas molar ratio and cyclic performance. Compared with Ce2(SO4)3, the X(CH4) can increase by 73.19%. Because it has a larger specific surface area (SSA) and less carbon deposition. The hierarchical pore structure provides an excellent micro-environment for the reaction. While the agglomeration of OC particles, the decrease in SSA and collapse of pore structure are important reasons for the decreasing trend of X(CH4). These results provide fundamental information on the reaction mechanism of 20NiO/30Ce2(SO4)3-50MgO, and present it as a promising candidate for CLPOM. |
