With the growing energy demand and depletion of fossil fuels, methane (CH4) conversion technologies have garnered attention to produce derivative fuels and chemicals. We propose a dual-phase and cobalt-free hollow fiber membrane (HFM) composed of Ce0.8Sm0.2O2−δ(SDC) and La0.8Ca0.2Al0.3Fe0.7O3−δ(LCAF) for oxy-CO2reforming of methane (OCRM) with production of syngas and pure N2. At 850 °C, the SDC–LCAF HFM demonstrated an oxygen permeation flow rate of 2.01 mL min−1with 10 mL min−1air feed and 10–10–20 mL min−1CH4–CO2–He permeate inlet flow rates. The SDC–LCAF membrane demonstrated excellent thermochemical stability and CO2resistance. When integrated with a 10 wt% Ni/SDC–LCAF catalyst, the OCRM performance of the resultant membrane reactor was achieved with high CH4and CO2conversions, and CO and H2selectivity of approximately 99.83%, 78.40%, 93.24%, and 83.76%, respectively. The reactor exhibited stable performance for 50 h, making it a promising solution for sustainable syngas and N2production. |
