Studies on the performance stability of mixed conducting BSCFO membranes in medium temperature oxygen permeation

A permeation study using bare Ba0.5Sr0.5Co0.8Fe0.2Ox membranes shows that stable oxygen fluxes are only achieved when operating the membrane at temperatures higher than 1023 K and indicates therefore that short contact time membrane reactors will be most suitable for future upgrading of light hydrocarbons.
