摘要：

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 mumol/min cm(-2) (2.5 cm(3)-std/min.cm(2)) at 1273 K and 0.3 mm thickness, Application of LSGF membrane for CH4 partial oxidation was further studied. Since the P-O2 difference became large, oxygen permeation rate drastically increased and it attained a value of 322 mumol/min cm(2) (8 cm(3)/min cm(2)) 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, (C) 2002 Elsevier Science B.V.
