A transition piece, connected to the reaction pipe, has a fork-shaped end portion composed of an inner portion and an outer portion with heat-insulating material between them. The outer portion is secured to the base of the supply chamber coaxially relative to the longitudinal axis of the cooling pipe. The supply chamber, transition piece and half shells form a prefabricated unit. An inner tube section is welded to, and extends out of, the supply chamber and is aligned with the inner portion of the transition piece. The inner tube section has a thickness, inner diameter and outer diameter corresponding to those of the inner pipe. The thickness, inner diameter and outer diameter of the half shells correspond to those of the outer pipe.

Abstract

The invention relates to a method for regenerating the oxygen permeability of a membrane containing an oxygen anion-conducting ceramic material. According to said method, the membrane, after an operating phase, is subjected to a regeneration phase in which the temperature of the membrane is increased above the temperature selected in the operating phase so that the oxygen permeability of the membrane rises again. The method can be used during the separation of oxygen from gases or for carrying out oxidation reactions in a membrane reactor and allows operation of said devices at temperatures of less than 800°C. The reactors used in this method have at least one device which allows the membrane to be heated by direct or indirect heat exchange.
