  • Patent number: 9174192
    Abstract: The invention relates to a tube bundle reactor with a flat feed hood. Alternatively, the release hood may also have a flat design. The flat design reduces the heat of reaction which arises in the hood in the case of reaction types which take place not only in the tube bundle (uncatalyzed reactions and reactions with homogeneously distributed catalyst). This greatly suppresses undesired reactions which already take place in the hood owing to accumulated heat, which achieves a higher selectivity in the case of thermally sensitive reactions. In addition, the thermal distribution within the hoods can be controlled precisely. The tube bundle reactor comprises a tube bundle which has a feed end which is connected to a feed hood of the tube bundle reactor, wherein the feed hood is configured in a flat design with a cross-sectional area at the feed end and an internal volume, and the ratio of internal volume to cross-sectional area is less than 0.35 m.

  • Patent number: 8721997
    Abstract: A process for continuous heterogeneously catalyzed partial dehydrogenation of at least one hydrocarbon to be dehydrogenated in a reactor which is manufactured from a composite material which consists, on its side in contact with the reaction chamber, of a steel B with specific elemental composition which, on its side facing away from the reaction chamber, either directly or via an intermediate layer of copper, or of nickel, or of copper and nickel, is plated onto a steel A with specific elemental composition, and also partial oxidations of the dehydrogenated hydrocarbon and the reactor itself.

  • Patent number: 8697016
    Abstract: A reactor in the form of an essentially horizontal cylinder for carrying out an autothermal gas-phase dehydrogenation of a hydrocarbon-comprising gas stream by means of an oxygen-comprising gas stream to give a reaction gas mixture over a heterogeneous catalyst configured as monolith is disclosed herein. The interior of the reactor is divided by a detachable, cylindrical or prismatic housing which is arranged in the longitudinal direction of the reactor, gastight in the circumferential direction and open at two end faces of the housing into an inner region, having one or more catalytically active zones. In each case, a packing composed of monoliths may be stacked on top of one another, next to one another, and above one another and before each catalytically active zone. Also in each case, a mixing zone having solid internals and an outer region arranged coaxially to the inner region are provided.

  • Publication number: 20110009627
    Abstract: The invention relates to a reactor for performing high-pressure reactions, comprising at least one tube (31) whose ends are each conducted through a tube plate (33) and which is bonded to the tube plate (33). The tube plates (33) and the at least one tube (31) are surrounded by an outer jacket, such that an outer space (39) is formed between the tube (31) and the outer jacket. The tube plates (33) each have at least one surface composed of a nickel-base alloy and the at least one tube (31) is in each case welded on to the surface composed of the nickel-base alloy. The surface composed of the nickel-base alloy points in each case in the direction of the particular reactor end. The outer jacket has a thickness which is sufficient to absorb tensile forces which occur between tube (31) and outer jacket owing to a temperature difference in the event of different expansion. The invention further relates to a process for starting up the reactor and for performing an exothermic reaction in the reactor.
