    Abstract: An electrocatalytic process is described for producing synthesis gas from light hydrocarbons such as methane or natural gas. The process generally comprises the steps of (A) providing an electrochemical cell comprising a solid electrolyte having a first surface coated with conductive metal, metal oxide or mixtures thereof capable of facilitating the reduction of oxygen to oxygen ions, and a second surface coated with conductive metal, metal oxide or mixtures thereof, provided that both coatings are stable at the operating temperatures, (B) heating the cell to a temperature of at least 1000 DEG C, (C) passing an oxygen-containing gas in contact with the first conductive coating, (D) passing methane, natural gas or other light hydrocarbons in contact with the second conductive coating, and (E) recovering synthesis gas.

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