A reactor casing (1, 1') is closed by end covers (2, 5), each with an opening (3, 6). Tube sheets (8, 30) are located in the upper and central regions. Upper and lower internal vessels (9, 34) are each located under a tube sheet, and define gas chambers (16, 38). The top internal vessel has basal openings (11). At right angles to the reactor casing and below the inner vessel, a partition is located, having openings (20) between the upper internal vessel and second tube sheet. It divides third- (21) and fourth- (24) gas chambers. Preferred Features: Openings make appropriate internal and external connections. Extraction tubes (17) are included in the first tube sheet (8), and reactor tubes (32) in the second (30). Extraction tubes extend through openings (11) into the reactor tubes. Reactor tubes are constructed partially as membrane tubes, the membrane section being located in the second gas chamber (38). The membrane region is a gas-tight, oxygen ion- and electron-conducting ceramic membrane, applied to the-gas permeable support tube. The region may comprise a monolithic ceramic tube of the same characteristics. The lower internal chamber is at least partially-filled with a granular catalyst. The reactor tube is coated with catalyst, at least in the membrane region. The reactor tubes extend through the base of the lower internal chamber, into the gas chamber (7) below. On the inside of the reactor casing and/or on the inside of the cover, a thermally-insulating layer is located. On the tube sheets, sections of pipe are arranged, into which the extraction- and or reactor tubes can be inserted. Near the openings (11), the extraction tubes have gas-tight metal bellows (18), connected at one end to the extraction tubes, preferably gas tight. The metal bellows are welded to the extraction tubes. Turbulence intensifiers are located in the first gas chamber, the second gas chamber, inside the extraction tubes, preferably inside the extraction tubes in the region of the first gas chamber and/or in the annular gaps (23) formed by the extraction tubes and the reaction tubes. The reactor is cylindrically-symmetrical.
