N2 - Fe doped LaGaO3 based perovskite oxide was investigated in this study as an oxygen permeating membrane for CH4 partial oxidation. La0.7Sr0.3Ga0.6Fe0.4O3 exhibits a high oxygen permeation rate from air to He as high as 102 μmol/min cm2 (2.5 cm3-std/min·cm2) at 1273 K and 0.3 mm thickness. Application of LSGF membrane for CH4 partial oxidation was further studied. Since the Po2 difference became large, oxygen permeation rate drastically increased and it attained a value of 322 μmol/min cm2 (8 cm3/min cm2) at 1273 K and 0.5 mm thickness. Catalyst for CH4 partial oxidation has a great influence on oxygen permeation rate through membrane and it became clear that Ni and Ru are highly active for CH4 partial oxidation.
