MEMBRANE AND ITS USE Russian patent published in 2003 - IPC

FIELD: tight single-phase membranes. SUBSTANCE: proposed single-phase tight membrane possess high ionic and electron conduction; it releases oxygen from oxygen-containing gas mixture where membrane is made from materials of mixed oxides of metals at excessive introduced oxygen presented by the following formula: , where A, A^, and A^,, are selected from groups 1, 2 and 3 and from lanthanides and B, B^,, B^,, and B^,,, are selected from transition metals according to periodic system of elements approved by IUPAC, where and each x and y is such number that y+y^,+y^,, = 2, x+x^,+x^,,, = 1, and δ is equal to number where 0≤δ≤1, thus indicating amount of excessive oxygen. Proposed membranes may be used for production of pure oxygen, enrichment of scavenge gas with oxygen , gas synthesis production, production of oxygen for any catalytic and non-catalytic processes. EFFECT: enhanced efficiency. 4 cl, 3 dwg, 3 ex
