Perovskite

An oxygen transport ceramic membrane was prepared with La0.6Sr0.4TixFe1–xO3–δ (x = 0.2 and 0.3) oxides which was synthesized by polymerized complex method. In order to investigate the effects of Ti substitutions into lanthanum–strontium ferrites, material property, thermal expansion coefficient, oxy

A membrane reactor with perovskite hollow fibres in combination with a commercial steam reforming catalyst is used to produce in a long term scale synthesis gas with a methane conversion of about 96%, a CO selectivity of 95% and at a H2/CO ratio of 2. By having the whole perovskite hollow fibre at 8

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

A La0.7Sr0.3Ga0.6Fe0.4O3-δ membrane with perovskite structure is fabricated by a conventional solid-state reaction. As the oxygen permeation flux of the La0.7Sr0.3Ga0.6Fe0.4O3-δ membrane was lower than commercial gas separation membranes, we coated a La0.6Sr0.4CoO3-δ layer to enhance the oxygen perm
