    @ Die Erfindung betrifft einen stehenden Reaktor zur Erzeugung von Methanol, mit einem zylindrischen Gehäuse mit das Katalysatorbett im Inneren des Gehäuses durchsetzenden Austauscherrohren, sowie einem das Katalysatorbett tragendem, gasdurchlässigen Boden oder Netz im unteren Reaktorabschnitt. Bei einem solchen Reaktor soll die Aufgabe gelöst werden, sowohl den Austausch der Katalysatorfüllung wie auch das Überwachen und Auswechseln der Wärmetauscherrohre in dem Katalysatorbett und das Ersetzen des Katalysatorbodens oder -netzes bei konstruktiv einfachem Reaktoraufbau durchführen zu können, wobei die Strömungsverhältnisse im Katalysatorbett verbessert werden. Hierzu ist vorgesehen, daß das Gehäuse (G) durch eine obere Haube (5) abgeschlossen ist und das Katalysatorbett von einem zylindrischen Mantel (13) innerhalb des Gehäuses umschlossen ist, der bei abgehobener Haube mit dem Katalysatorbett in Längsrichtung des Reaktors aus dessen Gehäuse (G) hsraushebbar ist. Die Austauscherrohre (22) sind mit radialen symmetrisch in die Strömungsräume ragenden Stiften (80) versehen.

    enclosed spaces. The crude gas enters the catalyst bed and is withdrawn after the reaction already in the form of gaseous methanol. Casing
    one
    The invention relates to a reactor design for the production of methanol can be used in the chemical industry.
    The aim of the invention is to ensure reliability of work by exercising control.
    FIG. 1 shows a first embodiment of a reactor with its active layer, a longitudinal section; on ig. 2 is another embodiment of the reactor, in which the inner space of the cylindrical casing accommodates two active layers; in FIG. 3, a cross section along the catalyst bed (catalyst beds) of both embodiments according to FIG. 1 and 2 | in fig. 4 - reactor, horizontal section; in fig. 5 is a section A-A in FIG. four. .
    The vertical reactor for producing methanol comprises a high-pressure body 1 with flanges 2, covered inside with an insulating layer 3, a cap 4, a bottom 5, also covered from the inside with an insulating layer 6 and 7, respectively. Inside the case there is a cylindrical housing 8 fixed in the lid 4, equipped in the lower part with a gas-permeable base 9 with a layer of catalyst 10 placed on it, inside which is placed a heat exchanger 11. The case B is made of fin tubes 12, the upper and lower ends of which end with thickened sections 13 , 14, to which the upper and lower ends of the tubes of the heat exchanger 11 are connected, respectively. The thickened sections 13 and 14 of the fin tubes of the casing 8 are connected respectively to the upper 15 and lower 16 ring headers. The tubes of the heat exchanger 11 are equipped with fins 12 and 13, the image of the closed spaces 14 in which the catalyst 10 is placed, and the rods symmetrically extending the fin tubes are fixed on the lid and can be removed from the reactor in the upward direction. 5 hp f-ly. 5 il.
    the closed spaces 14, which flow in a streamlined flow, with the rods of one space flowing around the flow are located at different heights along the length of their pipes and have a length equal to 1/4–1/3 of the distance between two diagonally arranged neighboring pipes. The reactor is equipped with a perforated transverse partition 16, on which an additional layer of catalyst is placed.
    The reactor works as follows. .
    The crude gas is fed through a conduit 17 fixed in the bottom 5, or via conduit 18 in the case of a reactor with two catalyst beds. The gas that has passed the catalyst 10 between the tubes of the heat exchanger 11 is removed after the reaction, which occurs through the catalyst, already in the form of gaseous methanol through conduit 19 or through conduits 20 and 21, fixed respectively in crest 4 and bottom 5. Closed around its perimeter cylindrical housing from fin tubes 12 closely adjoins insulating layer 3
    .reactor. After removing the cover 4 with its insulating layer 6, the heat exchanger 11 with the housing 8 and the mass of the catalyst can be removed from the reactor in an upward direction. After that at
    partially or completely removing the mesh or plate for the catalyst 10 a mass of the catalyst can be released and replaced with a fresh portion. The heat exchanger tubes 11, located outside the housing, can be easily removed down or up, and then re-installed. The cooling medium of the heat exchanger 11 is supplied through the pipe 22 passing through the bottom 5 and removed from
    ring collector 15 through one or more pipes 23.
