A contact tube bundle reactor (1), with partitioned headers (3, 4) allowing heat exchange medium supply to the lower header to be combined with co-current passage within the reactor, is new. A reactor (1) has: (a) a contact tube bundle (2), through the tube interspaces of which a circulating heat exchange medium is passed; (b) annular headers (3, 4) with side openings (5, 6) for pumped supply and return of heat exchange medium, part or all of which is optionally passed through an external heat exchanger, the heat exchange medium being supplied to the lower header (4) and returned via the upper header (3) to the pump; and (c) baffle plates (7) which leave a passage opening alternately at the reactor center and at the reactor edge. Each header (3, 4) is sub-divided by a cylindrical partition (8, 9) into inner (11, 13) and outer (12, 14) headers and the heat exchange medium of the outer lower header (14) is passed via an inner upper header (11) region outside the reactor and via its side openings (6) into the inner lower header (13) and then discharged through an outer upper header (12) region outside the reactor.
