| Abstract Scope |
Chemical looping dry reforming of methane (CLDRM) converts methane into syngas efficiently. SmFeO3 oxygen carriers were synthesized by the sol–gel method and investigated for CLPOM. Thermodynamic analysis indicated that SmFeO3 is thermodynamically favorable for syngas production between 665 and 950 ℃. Structural characterizations confirmed the formation of a stable orthorhombic perovskite phase with excellent redox stability after repeated cycles. Fixed-bed experiments demonstrated that the optimal reaction conditions were 900 ℃, 0.1 g oxygen carrier, a gas flow rate of 30 mL/min, and a reaction time of 16 min. Under these conditions, high methane conversion together with H2 and CO selectivities was achieved, yielding an H2/CO ratio close to 2. Moreover, SmFeO3 maintained stable catalytic performance during ten consecutive redox cycles, exhibiting excellent oxygen transfer capability and cyclic stability. These results demonstrate that SmFeO3 is a promising oxygen carrier for efficient syngas production via CLPOM. |
