Abstract
The present invention discloses a mixed ionic electronic conductor membrane comprising a dense layer sandwiched between two porous layers. Furthermore the invention discloses the application of this membrane to the use of partial oxidation of hydrocarbons. One porous layer, which is in contact with air, promotes the generation of oxygen ions. The oxygen ions diffuse through the dense layer to the second porous layer which is in contact with a hydrocarbon and result in partial oxidation of the hydrocarbon.
