    The reactor for conducting highly exothermic and endothermic catalytic processes comprises a housing 1, in which pipes and a catalyst are located, the casing being provided with a raw material nozzle 2 and outlet connection 3 for the finished product, and the pipes are located perpendicular to the axis of the reactor and design, 1.
    The invention relates to a reactor for conducting highly exo- and endothermic catalytic processes of partial oxidation, oxidative ammonolysis, oxidative dehydrogenation, and the like. and, more precisely, in the case of vapor-phase oxidation of o-xylene and / or naphthalene to phthalic anhydride, benzene or C-hydrocarbons
     to maleic anhydride, durol to pyromellitic anhydride, etc.
    A known reactor for conducting highly exo- and endothermic catalytic processes, comprising a casing, in which heat exchange sections and a catalyst, fittings for the input and output of the finished product are placed perpendicular to the axis (see ed.
    -sv. USSR number 52470, cl. 01 J 8/04, 1936).
     A disadvantage of the known device is that it is impossible to intensify the process and to provide an optimum temperature profile of temperatures.
    The aim of the invention is to intensify the process.
    The drawing shows the reactor.
    lengthwise cut.
    In accordance with the invention, a reactor for conducting highly eeo-and endothermic catalytic processes comprises a housing 1, in the upper and lower parts of which pipes are arranged, grouped into heat exchange sections 4, and between them are pipes, on the outer side of which a catalyst is applied, grouped into contact sections. 5, with the contact 5 and heat exchanging 4 sections arranged perpendicular to the axis, which are reacted successively by alternating groups of heat exchanging and contact ones. sections, with a catalyst applied to the outer surface of the pipes of the contact sections, and the casing is provided with side fittings 6 located opposite the contact sections. A zp f-ly, 1 ill.


    Torah. The catalyst can have the same or different composition. Heat exchangers 4 and contact 5 sections can be either smooth and finned or at an angle. The housing 1 is equipped with an upper fitting 2 and a lateral fitting 6 for feeding the raw material, as well as a leading fitting 3 for withdrawing the reaction products from the reactor.
    The reactor operates as follows. zom.
    The raw material is supplied through the upper fitting 2 and the lateral fittings 6, passes through the heat exchange sections 4, is heated to the required temperature, and then passes through the contact sections 5, in which the catalytic reaction takes place. The optimum temperature of the reactors is maintained with the help of a heat transfer fluid circulating inside the heat exchanging 4 and contact 5 sections, as well as with the help of the amount of input raw material through the upper 2 and lateral 6 nozzles. After passing through the contact sections 5, the reaction products are cooled to the required temperature, the passage through the heat exchange sections 5 and leave the reactor through the outlet connection 3.
