Description

Bei-katalytischen Umsetzungen in der Gasphase, wie bei der Dehydrierung oder Spaltung von Kohlenwasserstoffen, ist es bekannt, feste Katalysatoren durch den Reaktionsraum zu bewegen. Man verwendet zu diesem Zweck z. B. Rohre, in die der Katalysator oben durch eine Schleuse eingebracht lund aus denen er-unten durch eine weitere Schleuse abgezogen wird. Die mit dem Katalysator den Reaktionsraum durchströmenden Gase und ihre Umsetzungsprodukte treten dabei durch Schlitze in der Wiandung des Reaktionsrohres aus und werden getrennt von zudem Katalysator abgeführt. Bei dieser Arbeitsweise verstopfen sich nach einiger Zeit die für den Gasaustritt bestimmten Schlitze durch abgesplitterte Katalysatorteilchen und abgeriebenen Staub. In catalytic reactions in the gas phase, such as in dehydrogenation or splitting of hydrocarbons, it is known to use solid catalysts to move the reaction space. One uses for this purpose z. B. pipes into the The catalyst was brought in through a sluice at the top and from which it came through below another lock is withdrawn. The one with the catalyst is the reaction space The gases flowing through and their reaction products enter through slits the wall of the reaction tube and are discharged separately from the catalyst. With this method of operation, the gas outlet clogs after a while certain slots through broken catalyst particles and rubbed off dust.

Es wurde nun gefunden, daß sich diese Schwierigkeiten bei der Durchführung katalytischer Gasreaktionen unter Verwendung eines durch den Reaktionsraum bewegten Katalysators vermeiden lassen, wenn man das Reaktionsrohr, durch das sich der Katalysator bewegt, am unteren Ende mit einer Zackenkrone versieht un-d in eine der Austrittsschleuse vorgelagerte Trennkammer hiüefnragen läßt, in der sich der Katalysator frei böscht. Die Gase können so ungestört ohne die Gefahr einer Verstopfung entweichen. It has now been found that these difficulties in implementation catalytic gas reactions using a moving through the reaction space Avoid the use of the catalyst if you open the reaction tube through which the catalyst passes moved, at the lower end provided with a serrated crown and in one of the exit sluice upstream separation chamber can protrude, in which the catalyst is freely emptied. The gases can escape undisturbed without the risk of clogging.

-Eine beispielsweise Ausführungsform einer solchen Vorrichtung zeigt die Abbildung. Das Reaktionsrohr ii, durch das der Katalysator geschleust wird, besitzt am unteren Ende eine Zackenkrone 2, durch die die Gase in der durch die Pfeile angedeuteten Weise entweichen. Der Katalysator sammelt sich mit einer Böschung in der Trennkammer 3,-aus Ider er durch die Schleuse 4 austritt.- shows an example embodiment of such a device the illustration. The reaction tube ii, through which the catalyst is passed, has a serrated crown 2 at the lower end, through which the gases in the through the Escape in the manner indicated by the arrows. The catalyst collects with an embankment in the separation chamber 3, -from Ider it exits through the lock 4.

PATENTANSPRUCH: Vorrichtung zur Durchführung katalytischer Gasreaktionen, bei denen der Katalysator durch den Reaktionsraum bewegt wird, dadurch gekennzeichnet, daß das Umsetzungsrohr mit dem unteren, mit einer Zackenl;rone versehenen Ende in eine vor der Schleuse angebrachte Trennkammer hineinragt, in der sich der Katalysator löscht. PATENT CLAIM: Device for carrying out catalytic gas reactions, in which the catalyst is moved through the reaction chamber, characterized in that that the conversion tube with the lower, provided with a serrated end in a separating chamber in front of the sluice, in which the catalyst is located, protrudes clears.
