    Abstract: The invention proposes a reactor (1) having a contact tube bundle (2) through whose space surrounding the contact tubes a heat-exchange medium circuit is passed, with ring lines (3, 4) at both ends of the reactor with jacket apertures (5, 6) for the supply and discharge of a heat-exchange medium by means of a pump via an external heat exchanger, where the heat-exchange medium is fed to the lower ring line (4) and is discharged to the heat exchanger via the upper ring line (3), and with baffle plates (7) which leave a passage cross section alternately in the reactor center and at the reactor edge. The upper (3) and lower (4) ring lines are each divided into an inner (11, 13) and an outer (12, 14) ring line by a cylindrical partition wall (8, 9), and the heat-exchange medium is fed to the outer lower ring line (14), via a region outside the reactor to the inner upper ring line (11), via the jacket apertures (5) of the latter to the region surrounding the contact tubes (2), via the jacket apertures (6) to the inner lower ring line (13) and subsequently via a region outside the reactor to the outer upper ring line (12).

    Abstract: A multitube fixed bed reactor and the use of such a reactor for carrying out catalytic gas-phase reactions, in particular for carrying out exothermic and endothermic catalytic gas-phase reactions such as the preparation of phthalic anhydride (PA), acrylic acid, methacrylic acid (MAA), acrolein, maleic anhydride (MA), glyoxal, phosgene, hydrocyanic acid or vinyl formamide (VFA). In a relatively large multitube reactor in which a large amount of heat of reaction is generated owing to the numerous catalyst tubes ( 17 ) and has to be removed, it is proposed that the ratio of tube spacing t to external tube diameter d a be made dependent on the reactor diameter or on the external tube bundle diameter d RBa . At an external diameter of the catalyst tube bundle ( 18 ) of more than 4 meters, a ratio of tube spacing d to external tube diameter d a of at least 1.3 is preferred.

    Abstract: The invention relates to a reactor for partial oxidation of a fluid reaction mixture in the presence of a heterogeneous particulate catalyst. Said reactor comprises one or several cuboid heat-transfer sheet modules (1) which are each composed of two or several right-angled heat-transfer sheets (2), arranged parallel to each other such as to form a slit (3) which can be filled with the heterogeneous particulate catalyst and through which the fluid reaction mixture flows, the heat of reaction being absorbed by a heat carrier which flows through the heat-transfer sheets (2) and at least partially evaporates. Said reactor also comprises a mainly cylindrical envelope (4, 15, 16) which depressurizes the heat-transfer sheet modules and fully surrounds said modules, said envelope being composed of a cylinder casing (4) and of caps (15, 16), closing said casing at both ends, the longitudinal axis of which extends parallel to the plane of said heat-transfer sheets (2). Said reactor finally comprises one or several sealing elements (7, 23), arranged so that the fluid reaction mixture flows only through the slit (3), except through the reactor interior spaces, defined by the caps (15, 16).
