Abstract
Description
Die vorliegende Erfindung betrifft weitere vorteilhafte Ausgestaltungen, die zur Niederhaltung von angeströmten festen Katalysatorpartikeln in einem Reaktor zur Durchführung von katalytischen Gasphasenreaktionen dienen, wie sie in der Anmeldung
Ein organischer Schaum wie z. B. Polyurethan kann mit Metallpulver, Wasser und Binder Suspension beschichtet, und anschließend mittels Wärmebehandlung zum Metallschaum verarbeitet werden. Unter den bekannten Verfahren wird das SRSS-Verfahren (Schlickerreaktionsschaumsinter) häufig angewandt. Zum Herstellen des Metallschaums kann nach dem Ermessen des Fachmanns die jeweils angemessene Methode benutzt werden.An organic foam such. B. Polyurethane can be coated with metal powder, water and binder suspension, and then processed by heat treatment to metal foam. Among the known methods, the SRSS method (slurry reaction foam sinter) is widely used. To produce the metal foam, the appropriate method may be used at the discretion of the skilled person.
Ein offenporiger poröser Metallschaum mit zufälligen Poren wird als Schichtelement für die Katalysatorhaltevorrichtung verwendet.An open-pore porous metal foam with random pores is used as a layer member for the catalyst holding device.
Die Porengröße des Metallschaums kann herstellungsbedingt variiert werden, so dass der Metallschaum unterschiedliche Porengrößen auf beiden Seiten haben kann. Je nach der Größe der Katalysatorpartikel kann der Metallschaum beim Herstellen so gestaltet werden, dass der Metallschaum auf der der Katalysatorschüttung zugewandten Seite kleinere Poren hat als der kleinste Querschnitt der vorgesehenen Katalysatorpartikel. Dadurch werden die Katalysatorpartikeln in dem durch den Metallschaum eingegrenzten Katalysatorbett festgehalten. Mit hoher Geschwindigkeit strömt das Reaktionsgas durch die Haltevorrichtung aus Metallschaum in das Katalysatorbett. Größere Poren auf der Katalysatorschüttung abgewandten bzw. der gaszuströmenden Seite des Metallschaums bewirken einen verringerten Druckverlust und begünstigen die Durchströmung des Gases.The pore size of the metal foam can be varied as a result of the production, so that the metal foam can have different pore sizes on both sides. Depending on the size of the catalyst particles, the metal foam may be designed during manufacture in such a way that the metal foam on the side facing the catalyst bed has smaller pores than the smallest cross section of the catalyst particles provided. As a result, the catalyst particles are held in the catalyst bed bounded by the metal foam. At high speed, the reaction gas flows through the metal foam holding device into the catalyst bed. Larger pores on the side facing away from the catalyst bed or the gas-flowing side of the metal foam cause a reduced pressure loss and favor the flow through the gas.
Wie die keramischen Elemente lassen sich die Metallschaum-Segmente auch so anordnen, dass sich eine geschlossene gasdurchlässige Schicht bildet. Im Vergleich zum starren und spröden keramischen Element besitzt der Metallschaum aber hohe spezifische Steifigkeit und Festigkeit, und ist ein wenig biegsam. Bei der lokal unterschiedlichen Legung der Katalysatorschüttung führen die Segmente der Metallschäume die Katalysatoroberfläche nach, jeweils unabhängig von den anderen Segmenten, darum entsteht auch kein Freiraum zwischen dem Katalysatorbett und den abdeckenden Metallschäumen, trotz der Unebenheit der Katalysatorschüttung. Einzelne Segmente der Metallschäume können über weitere Fügeverfahren zusammengesetzt werden. In einer vorteilhaften Gestaltung enthält der Metallschaum Führungsnuten, die als Verbindung zueinander dienen, über die Führungsnuten können die Metallschäume leicht ein- und ausgebaut werden. Der Metallschaum lässt sich bei der Herstellung mit Haken oder Ösen gestalten, um die einzelne Segmente miteinander zu einer bündigen Schicht verbinden zu können, ebenso kann der Metallschaum auch mit Schrauben verbindbar vorgesehen werden, darüber hinaus kann der Metallschaum auch durch Schweißen oder Kleben verbindbar gestaltet werden.Like the ceramic elements, the metal foam segments can also be arranged so that a closed gas-permeable layer is formed. However, compared to the rigid and brittle ceramic element, the metal foam has high specific rigidity and strength, and is slightly flexible. In the case of locally different laying of the catalyst bed, the segments of the metal foams follow the catalyst surface, in each case independently of the other segments, therefore there is no free space between the catalyst bed and the covering metal foams, despite the unevenness of the catalyst bed. Individual segments of the metal foams can be assembled by further joining methods. In an advantageous embodiment of the metal foam contains guide grooves that serve as a connection to each other, on the guide grooves, the metal foams can be easily installed and removed. The metal foam can be designed in the production with hooks or eyes in order to connect the individual segments together to form a flush layer, as well as the metal foam can be provided connectable with screws, moreover, the metal foam can also be made connectable by welding or gluing ,
Eine Haltevorrichtung aus dem Schichtelement vom Metallschaum kann auch in Radialreaktoren eingesetzt werden. Eine bündige Schicht von Metallschäumen mit dem festzuhaltenden Katalysatorbett wird parallel zur Reaktorwand angeordnet, die Reaktionsgase strömen radial durch die Haltevorrichtung und Katalysatorbett.A holding device made of the layer element of the metal foam can also be used in radial reactors. A flush layer of metal foams with the catalyst bed to be held is placed parallel to the reactor wall, the reaction gases flow radially through the fixture and catalyst bed.
Die erfindungsgemäße Ausgestaltung wird anhand einer Zeichnung näher erläutert.
Die Haltevorrichtung besteht aus einer Zusammensetzung der einzelnen Segmente von Metallschäumen. In
Bei diesem Ausführungsbeispiel kann man sogar auf die Bohrungen verzichten, die Stifte können direkt auf die Metallschäume geschweißt oder geklebt werden, wobei die erfindungsgemäße Verwendung der Haltevorrichtung aus Metallschaum nicht auf solche Ausführungsform beschränkt ist.In this embodiment, one can even dispense with the holes, the pins can be welded or glued directly to the metal foams, wherein the inventive use of the holding device made of metal foam is not limited to such embodiment.
