Quarterly Technical Progress Report
The temperature dependence of the oxygen flux across the BaCe0G03 dense membrane (BCG membrane) tube was investigated. In the temperature range of 688C to 955C, the increase in the oxygen flux with temperature obeyed the Arrhenius law. An increase in the helium sweep flow membrane tube. rate in the tube side resulted in an increase in the oxygen flux through the The oxygen fluxes through the BCG dense membrane tube were measured at different oxygen partial pressures in the shell side. The oxygen flux increased with the oxygen partial pressure in the shell side. The BCG dense membrane was tested in a membrane reactor for the catalytic oxidative coupling of methane. The BCG membrane is not a complete combustion catalyst, and the catalytic activity of the BCG membrane was found to be much higher than the Argonne dense membrane. As the oxygen partial pressure in the shell side increased, the C2 decreased while the C2 yield remained unchanged, indicating that non-selective, reactions still played a significant role in the membrane reactor.
