  • the object is achieved by a method for installing monoliths, each formed of a ceramic block having a plurality of mutually parallel channels, which are flowed through by the reaction gas mixture of the heterogeneously catalyzed gas phase reaction in a reactor for carrying out heterogeneously catalyzed gas phase reactions, wherein the Monoliths side by side and one above the other, in the reactor interior, are stacked, which is characterized in that the monoliths are sealed against each other and the inner wall of the reactor by means of mats, comprising in each case a Blähmatte, wrapped on all sides in a plastic film prior to installation in the reactor wherein the space enclosed by the plastic film and containing the mat is vacuum-sealed and wherein the space enclosed by the plastic film and containing the mat interior is de-vacuumed after installation in the reactor.
  • the interior containing the mat can in particular be vacuum-evacuated by piercing and / or burning off the plastic film.
  • Monoliths for use in reactors for carrying out heterogeneously catalyzed gas phase reactions are known and described, for example, in WO-A 2012/084609.
  • Monoliths are formed from a ceramic material coated with catalytically active material.
  • the monoliths are installed in the reactor in one or more horizontal layers side-by-side, with vertically arranged channels, such that each layer completely fills the reactor cross-section, and spacers are provided between successive layers, keeping cavities clear the measuring elements, in particular for a temperature measurement, can be introduced.
  • the reaction mixture of the heterogeneously catalyzed gas phase reaction flows in the vertical direction, through the vertically arranged channels of the monoliths.
  • spacers for example, sheet metal strips with a width of in particular 10 to 30 mm between each two consecutive horizontal layers of monoliths are installed, so that they have a distance corresponding to the width of the metal strip.
  • the metal strips may preferably be angled; This increases their rigidity and they can carry higher weights.
  • the monoliths are incorporated into the reactor in such a way that mutually parallel channels thereof are arranged horizontally in the reactor.
  • two or more monoliths are arranged side by side and / or one above the other, with channels aligned parallel to one another and enveloped on the outer periphery thereof, in the longitudinal direction of the channels, with a metal rim, forming a monolith module.
  • the monolith modules are installed in the reactor with horizontally arranged channels.
  • two or more monolith modules are advantageously stacked on top of one another to form monolith module stacks. It is also possible to increase the capacity or, in order to achieve the desired conversion, install two or more monolith module stacks in succession in the reactor.
  • the monoliths comprising metal monoliths preferably extend slightly beyond the monoliths at both ends, in particular by about 5 to 10 mm.
  • the metal rim acts as a spacer between them when stacking monolithic sheets.
  • in the cavity thus kept free, it is possible, in a simple manner, to introduce multi-thermocouples for the temperature measurement through holes and / or holes in the protruding edge of the metal rim.
  • the respectively opposite sides of the metal enclosure in front of and behind the monoliths are welded together by means of metallic webs, so that a mechanical stability of the monolith module enveloped by the metal enclosure is ensured.
  • the metal rim can be made thinner.
  • the modular design ensures easier handling when installing and removing the monoliths in the reactor.
  • the service life of the reactors can be increased since exchange systems can be prepared for the catalyst change outside the reactor.
  • the monolith modules can easily be inserted into the reactor via guide rails and pulled out.
  • the presently used mat is a sheet with two opposite large surfaces and two perpendicular thereto arranged end faces.
  • the mat comprises a Blähmatte, ie a fiber mat, which expands (swells) at high temperatures.
  • Blähmatten are usually composed of silicates, such as aluminum silicate, an expanding mica, such as vermiculite, and an organic binder. Blähmatten be marketed for example by the company 3M under the trade name INTERAM®.
  • the organic binders have a number of adverse properties, in particular they lead to odor nuisance by evaporation of volatile components, such as poisoning of catalysts.
  • the mat consists exclusively of a Blähmatte.
  • the Blähmatte is a composite mat, which in addition to a Blähmatte a fiber mat of oxide fibers, in particular of alumina, which is lighter and more pressure resistant to a Blähmatte, has a lower thermal conductivity and up to about 1 .200 ° C. is temperature resistant.
