摘要: 2093332 9205862 PCTABS00011 Oxygen is separated from an oxygen-containing gas by introducing the into a first zone (1) of separation apparatus, apparatus comprising and second (2) zones mixed metal oxide membrane (8), (8) having surface (7) open to (1), (10) (2), empirical formula Bi Ax My Mz' On, where A at least one Mg, Ca, Sr, Ba, Y, Th, U, lanthanide elements; M Sc, Ti, Cr, Mn, Fe, Ni, Cu Zn; M' Co, Rh, Pd, Pt or Ru. The oxygen can be recovered either as molecular oxygen, it reacted with oxygen-consuming substance, such hydrocarbon gas, which introduced brought in contact (8).
