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: A reactor having a contact tube bundle, has a heat exchange agent recycle loop fed through the chamber surrounding the tubes with a throttle disk in the chamber surrounding the tubes is characterized in that filler particles are contained within the cavity between the throttle disks. A reactor (1) having a contact tube bundle (2), has a heat exchange agent recycle loop fed through the chamber surrounding the tubes, with ring tubing (3,4) at both reactor ends with openings (5,6) in the shell for the addition and/or removal of a heat exchange agent by means of at least one pump optionally by passage of at least part of the heat exchange agent via at least one external heat exchanger whereby the heat exchange agent is added via the lower ring tubing (4) and fed back via the upper ring tubing (3) to the pump(s) with a throttle disk (7,8) in the chamber surrounding the tubes at the height of the lower and upper ring tubing (3,4) and is characterized in that filler particles are contained within the cavity between the throttle disks (7,8).

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: Oxidation reactor (1) has a bundle of tubes (2) for flowing ingredients, surrounded by a heat chamber containing a heat medium. The upright heat chamber ends have inlet and outlets linked by a ring-flow (4, 5) pipes a pump (8) driven by a vertical shaft (9). Oxidation reactor (1) has a bundle of tubes (2) for flowing ingredients, surrounded by a heat chamber containing a heat medium. The upright heat chamber ends have inlet and outlets linked by a ring-flow (4, 5) pipes a pump (8) driven by a vertical shaft (9). The pump has diagonal-action impeller (10) blades with a heat medium (3) throttle gap (11) parallel to the shaft (9), on the pressure side of the pump. Some of the hot medium is drawn from the upper ring pipe (4), passes through one or more external heat exchangers, and is then returned to the lower ring pipe (5). The gap produces a leak current of preferably 5 to 10% of total flow (3). Some of the leaked (11) hot medium is surrendered to the pump inlet side. On the pump inlet side the impeller seal acts as a hydrodynamic bearing (13). The pump has a spiral egress. The reactor heat chamber incorporates a number of baffle plates (12).
