High oxygen permeation rate in La0.6Sr0.4Ti0.3Fe0.7O3 thin membrane on a porous support with multichannel structure for CH4 partial oxidation / Akihiro Kawahara in Industrial & engineering chemistry research, Vol. 49 N° 12 (Juin 2010)

A LSTF thin membrane with 60 μm thickness was successfully prepared on the multichannel support with 30% porosity. The oxygen permeation rate was much improved by using the multichannel structured support, as the permeated oxygen was removed rapidly. On the other hand, partial oxidation of CH4 into CO and H2 is dominant on the LSTF membrane. The oxygen permeation rate increased as the thickness of the membrane and the porous support decreased, and a value of 13.3 cm3/(min cm2) was achieved at 1273 K under a CH4 partial oxidation condition.
