Methane Partial Oxidation Using A (La0.6Sr0.4)(Ga0.8Mg0.05Co0.15)O3–δ Membrane.

This article describes results on methane partial oxidation in (La0.6Sr0.4)(Ga0.8Mg0.05Co0.15)O3 ceramic membrane reactors. The thin membranes were fabricated by co-firing with porous composite NiO–La-doped Ceria (LDC) supports. A La0.6Sr0.4Fe0.2Co0.8O3-based composite layer on the air side of the membrane promoted fast oxygen reduction. Electrical measurements indicated that LSGMC showed good mixed conductivity and that oxygen transport was co-limited by bulk and interfacial processes. The O2 permeation rate during methane partial oxidation at 750 °C was ≈10–12 sccm/cm2, with a maximum syngas production rate of 60–70 sccm/cm2. [ABSTRACT FROM AUTHOR]
