Abstract (en)
[origin: WO2011079913A1] The invention relates to a method for controlling the permeation rate of oxygen through a non-porous ceramic membrane which conducts oxygen anions and which contains alkaline earth ions. Carbon dioxide and/or a gaseous carbon dioxide precursor is added for a specified time on at least one face of the non-porous ceramic membrane which conducts oxygen anions, said addition enabling a change in the oxygen permeability of the membrane material. This causes a reversible chemical formation of alkaline earth carbonates in the membrane and thereby changes the properties thereof for the permeation of oxygen. A membrane reactor designed with a feed line for a moderating gas can be controlled in a simple manner. The membrane reactor can be advantageously adjusted for oxidation reactions or for separating oxygen from gas mixtures.
