Abstract

For practical application in syngas production, the oxygen permeable membranes should possess both high oxygen permeation flux and good stability in harsh environment (CO₂-containing reductive atmosphere). Under the premise of keeping stability, anion-doping method was applied to improve the oxygen permeability of the CO₂-stable (Pr_0.9La_0.1)_2.0(Ni_0.74Cu_0.21Ga_0.05)O_4+δ ((PL)_2.0NCG) membrane. The developed (Pr_0.9La_0.1)_2.0(Ni_0.74Cu_0.21Ga_0.05)O_4+δCl_0.1 ((PL)_2.0NCGCl_0.1) exhibited three times higher oxygen permeation fluxes, similar CO₂-tolerance and long-term stability compared with its parent one. Furthermore, the (PL)_2.0NCGCl_0.1 membrane was constructed to be used in reactors for the syngas production through partial oxidation of methane, which showed an oxygen permeation flux of 5 mL/min cm², a methane conversion of 99.9%, and a CO selectivity of 97.5% at 900 °C, and no any degradation was observed during 100 h.
