Vorrichtung und Verfahren zur Regelung der Sauerstoffpermeation durch nicht-poröse Sauerstoffanionen leitende keramische Membranen und deren Verwendung

Beschrieben wird ein Verfahren zur Regelung der Geschwindigkeit der Permeation von Sauerstoff durch eine nicht-poröse Sauerstoffanionen leitende keramische Membran enthaltend Erdalkaliionen, die auf beiden Seiten von einem Sauerstoff enthaltenden Gas umgeben ist. Dabei wird das Gas auf mindestens einer Seite der Membran für eine vorbestimmte Zeit bei Temperaturen zwischen 400 und 900°C ganz oder teilweise durch ein Kohlendioxid enthaltendes Moderatorgas ersetzt. Dieses bewirkt eine reversible chemische Ausbildung von Erdalkalicarbonaten in der Membran und verändert dadurch deren Eigenschaften für die Sauerstoffpermeation. Ein mit einer Zuleitung für ein Moderatorgas ausgestalteter Membranreaktor kann auf einfache Art und Weise geregelt werden. Der Membranreaktor lässt sich vorzugsweise für Oxidationsreaktionen oder zur Abtrennung von Sauerstoff aus Gasgemischen einsetzen.

DEVICE AND METHOD FOR CONTROLLING THE PERMEATION OF OXYGEN THROUGH NON-POROUS CERAMIC MEMBRANES WHICH CONDUCT OXYGEN ANIONS, AND THE USE THEREOF

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.
