Can inorganic membranes compete with organic ones? Perovskite hollow fibres for O2-separation and supported H2-selective zeolite membranes

So far, large scale industrial separations with inorganic membranes and catalytic membrane reactors in process intensification do not exist. Two prominent developments which are near to a commercialization are discussed: perovskite membranes for oxygen separation and zeolite membranes for molecular sieving.
