The present invention relates to a jacket tube reactor for carrying out a catalytic gas phase reaction, comprising a catalyst tube bundle (8) and a gas inlet hood or a gas outlet hood (2, 60). This bundle of catalyst tubes has a corresponding reaction gas mixture flowing therethrough, is provided with a catalyst filling, extends between the two tube plates (4, 148), and in the reaction tube jacket (6) surrounding it, the contact flow of the heat medium. In addition, the gas inlet hood or the gas outlet hood is stretched over both the tube plates, supplies the corresponding process gas to the catalyst tube bundle, and discharges the reacted process gas from the catalyst tube. . This jacketed tube reactor, together with all its components in contact with the process gas, is characterized in that it is designed to withstand the explosion pressure or detonation pressure that must be taken into account in terms of its operating conditions in terms of strength. Preferably, the volume applied to the process gas mixture before the catalyst tube inlet should be kept as small as possible from a design and fluidics point of view. By using the corresponding reactor, it is possible to increase the amount of the process gas supplied for the treatment and the amount of the process gas containing a component that may explode in an economical manner without risk. And at the time of starting of a reactor, it can pass through the explosion danger range in the gas composition from that time. |
