    Abstract: Reactor (1) para ensayar sistemas catalíticos con tubos de contacto (2), dispuestos paralelamente entre sí en un recinto para la reacción, que están soldados en sus extremos con platos para tubos, así como con caperuzas (3) en ambos extremos del reactor, que limitan, respectivamente, un recinto de la caperuza (4), alimentándose a los tubos de contacto (2) un medio de reacción fluido (5) a través de un recinto de la caperuza (4), que recorre los tubos de contacto (2) y que se descarga a través de otro recinto de la caperuza (4) así como con un circuito cerrado para el agente intercambiador de calor con alimentación del agente intercambiador de calor (6) en un extremo del reactor, paso a través del recinto intermedio comprendido entre los tubos de contacto (2) y descarga por el otro extremo del reactor, caracterizado porque los tubos de contacto (2) están dispuestos, agrupadamente, en dos o varias zonas de tubos de contacto (7), separadas térmicamente entre sí.

    Abstract: In a reactor (1) which has a bundle of catalyst tubes (2) and in which a heat transfer medium is circulated through the space surrounding the catalyst tubes, with the ring lines (3, 4) at both ends of the reactor with openings (5, 6) through the wall for introduction or removal of a heat transfer medium by means of one or more pumps, where the heat transfer medium is introduced into the lower ring line (4) and is returned via the upper ring line (3) to the pump(s) and the heat transfer medium or a substream of the heat transfer medium may, if desired, be passed over one or more external heat exchangers, and with deflecting plates (7) which alternately leave free an open cross section in the middle of the reactor and at the edge of the reactor, the lower ring line (4) is divided by means of a horizontal dividing wall (8) into two regions between which material can pass via preferably uniformly distributed openings (9) having a regulatable open cross section.

    Abstract: A reactor (1) for preparing phosgene by gas-phase reaction of carbon monoxide and chlorine in the presence of a solid catalyst, which reactor has a bundle of parallel catalyst tubes (2) aligned in the longitudinal direction of the reactor whose ends are fixed in tube plates (3) and have a cap (4) at each end of the reactor (1), and has deflection plates (6) which are aligned perpendicular to the longitudinal direction of the reactor in the intermediate space (5) between the catalyst tubes (2) and leave free passages (7) located alternately opposite one another on the interior wall of the reactor, and in which the catalyst tubes (2) are charged with the solid catalyst, the gaseous reaction mixture is passed from one end of the reactor via one cap (4) through the catalyst tubes (2) and is taken off from the opposite end of the reactor (1) via the second cap (4) and a liquid heat transfer medium is passed through the intermediate space (5) around the catalyst tubes (2), where the reactor (1) has no tubes in the region of the passages (7), is proposed.

    Abstract: A process for coating internals in a reactor, except for the coating of electrically heatable, at least partly open-cell foams, with a catalytically active material or a precursor thereof, in which an aerosol which contains the catalytically active material or the precursor thereof as a disperse phase is provided and the aerosol is passed through the reactor at a rate in the range from 0.1 to 4 m/s, which is established so that the disperse phase of the aerosol is deposited on the internals in the reactor.

    Abstract: The invention relates to a method for coating internal fittings in a reactor , except for electrically heatable, at least partly open-cell foams, with a catalytically active material or a precursor therefor. According to said method, aerosol containing the catalytically active material or the precurso r therefor as a dispersed phase is provided and is directed through the reacto r at a speed which is set in such a way that the dispersed phase of the aeroso l deposits on the internal fittings of the reactor.

    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 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).
