Curtin is ready to partner with industry to bring this technology to full commercial implementation. Curtin is seeking licensees for this technology, notably companies with interest in the manufacture of ceramic ion transport membranes. We are also interested in ongoing research collaboration in the optimisation of the membrane, and development of its applications.
Summary of technology
Oxygen can be separated from air using a ceramic ion transport membrane, a device permeable only to oxygen. Commercial efforts to use this technology in oxygen production and other applications have so far failed due to insufficient rates of oxygen transport, or flux.
Researchers at Curtin University have developed a uniquely structured ceramic ion transport membrane for oxygen separation that shows remarkably high flux. The membrane employs a multitude of microchannels extending into the depth of the membrane, rather than the conventional structure, which limits flux.
Membranes manufactured in the laboratory from the high-performance ceramic BSCF separated oxygen from air at a rate of 11.3 mL/min.cm2 at 1000 °C, which is considerably higher than any flux rate that has previously been reported. Trials on the cheaper and more commonly used material LSCF gave a flux rate of 3.98 mL/min.cm2 at 1,050 °C.
