Abstract

The effect of surface modification on the oxygen separation properties of permeation membranes is investigated in this work. For this purpose, dense perovskite type membranes of the composition Ba_0.5Sr _0.5Co_0.8Fe_0.2O_3-δ have been successfully prepared by polymerized complex method. Oxygen permeation experiments were conducted according to membrane thickness (1.0 mm and 1.6 mm) and surface modification. The surface modification of the Ba _0.5Sr_0.5Co_0.8Fe_0.2O _3-δ dense membranes for measurement of oxygen permeability was done mainly by screen printing technique Ba_0.5Sr_0.5Co _0.8Fe_0.2O_3-δ powders. The oxygen flux of Ba_0.5Sr_0.5Co_0.8Fe_0.2O _3-δ membrane increased with increasing temperature and with decreasing membrane thickness. The oxygen permeation flux through 1.0 mm membrane thickness with modified surface exposed to flowing air (Ph=0.21 atm) and helium (Pl=10^-5 atm) was ca. 1.4 ml/cm²·min at 950 °C.
