Novel Nanocomposite Materials Based On Praseodymium Nickelate-Cobaltite for Oxygen Separation Membranes

Add time:08/01/2019    Source:sciencedirect.com

The key problems in developing catalytic membranes for producing syngas from biofuels by selective oxidation with oxygen separated from air are design of materials for functional layers and optimization of techniques of their deposition. Nanocomposite materials based upon praseodymium nickelate-cobaltite are promising for these purposes due to their high oxygen mobility provided by the fast oxygen diffusion channel. The oxygen permeability of membrane obtained meets criteria of the practical application. Syngas yield and methane conversion increase with temperature and contact time. Stable performance of the membrane was demonstrated for at least 200 h time-on-stream.
