Einsatz von perowskitischen Hohlfasermembranen in einem MikrowellenplasmaUse of Perovskite Hollow Fiber Membranes in a Microwave Plasma
For the first time the combination of a separation process with a plasma process was successfully tested. In this case, a mixed-conducting perovskite membrane separates the oxygen. At 1 kW a permeation of 2.24 mL min(-1)cm(-2) could be achieved. Corresponding perovskite membranes have been manufactured as hollow fibers with a very good CO2 stability. The hollow fibers showed a constant permeation over more than 200 h. Furthermore, a spinning process with a sulphur-free polymer binder has been established.
