Dense ceramic membranes with mixed, electron and oxygen-ion, conductivity are able to separate oxygen from air and other gas mixtures that contain oxygen in the form of individual molecules or gaseous oxides. This feature can be used in catalytic reactors in order to integrate oxygen separation and oxidation of gaseous organics. The method is currently considered as one of the most promising approaches for the development of novel energy efficient, environmentally friendly and compact technologies for processing of natural gas and related raw materials such as associated petroleum gas and biogas. The present report deals with general problems that emerge at practical implementations of ion-electron oxygen separating membranes in reactors for the primary processing of light hydrocarbons. The main demands for materials and process organization are considered. Particular attention is given to the partial oxidation of methane to synthesis gas. Keywords: mixed conductors, oxygen flux density, ceramic membrane, partial oxidation of methane, selectivity, conversion, synthesis gas.
