Methane partial oxidation using a (La0.6Sr0.4)(Ga0.8Mg0.05Co0.15)O3-δ membrane

This article describes results on methane partial oxidation in (La(0.6)Sr(0.4))(Ga(0.8)Mg(0.05)Co(0.15))O(3) ceramic membrane reactors. The thin membranes were fabricated by co-firing with porous composite NiO-La-doped Ceria (LDC) supports. A La(0.6)Sr(0.4)Fe(0.2)Co(0.8)O(3)-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 O(2) permeation rate during methane partial oxidation at 750 C was approximate to 10-12 sccm/cm(2), with a maximum syngas production rate of 60-70 sccm/cm(2).
