Definitions

  • the present invention relates to a method for exchanging catalytic material in tubular reactors, which is characterized in that, after the emptying of the catalyst material and before the new catalyst material has been filtered, the emptying carried out is controlled using one or more light sources.
  • tube-bundle reactors are frequently used.
  • An example is, in particular, the selective oxidation of hydrocarbons on fixed-bed catalyst charges. Since these reactions are exothermic, it is necessary that the heat of reaction be removed from the reactor as efficiently as possible. An uncontrolled reaction would increasingly produce unwanted by-products and expensive starting materials would be destroyed.
  • the supported catalysts usually consist of an inert support and a catalytically active material which has been applied to the support.
  • the object of the present invention was therefore to find an improved method for exchanging catalyst materials in tubular reactors, which eliminates the disadvantages mentioned and thus minimizes the said renewed emptying of already refilled reactor tubes.
  • a method has been found which is characterized in that, after emptying the catalyst material and before filling the new catalyst material, the emptying carried out is controlled using one or more light sources.
  • one or more light sources are arranged below the reactor tubes, ie in the lower reactor hood.
  • the light sources are advantageously arranged so that the light sources fully illuminate the reactor bottom and that the light sources can be perceived by the empty tubes on the upper tube sheet.
  • the control of the emptying of the reactor tubes can therefore according to the invention be carried out visually without aids.
  • the space below the reactor tubes prior to the arrangement of the light sources, is designed with hay material, preferably with white paper or white foil.
  • All light sources common to the person skilled in the art can be used as light sources, for example halogen and / or neon light and / or incandescent lamps.
  • Reactor tubes through which the light source is not or only partly visible from the top of the tube, contain spent catalyst or other contaminants. These reactor tubes are advantageously marked with a visually marked closure. After the control, the marked reactor tubes are advantageously emptied and / or cleaned.
  • the marked tubes are advantageously illuminated with a further light source from the upper reactor bottom.
  • the identification takes place, for example, as described in the German application with the file reference 102005027060.3 under the title "Process for filling pipe reactors" with colored plugs.
  • Tubular reactors commonly used are tube bundle reactors, as are known in the art for catalytic gas phase oxidations.
  • the catalyst material used may be any of the catalyst compositions known to those skilled in the art.
  • the time required for the method according to the invention is insignificant in comparison to the subsequent correction work.

Abstract

L'invention concerne un procédé pour remplacer le matériau catalyseur contenu dans des réacteurs tubulaires. Ce procédé est caractérisé en ce qu'il consiste à vérifier si le matériau catalyseur a été retiré des réacteurs tubulaires avec succès, à l'aide d'une ou de plusieurs sources lumineuses, dès l'achèvement du processus de retrait et avant le remplissage des réacteurs tubulaires au moyen d'un nouveau matériau catalyseur.
