Definitions

• the invention relates to a method and apparatus for injecting oxygen into a synthesis reactor, for example for oxydehydrogenation, with substantially axial flow through the gas mixture through a catalyst bed.
• this object is achieved according to the invention in that the oxygen is supplied to a arranged above the catalyst bed ring distribution system and is launched from a plurality of outlet openings in the ring manifold in a deviating from the vertical oblique angle to the catalyst surface.
• the oxygen in Pure form, present as air or mixed with inert gas or water vapor.
• Another method embodiment is that the atomization of the oxygen in a plane about 50-300 mm takes place above the catalyst bed, which ensures an oxygen residence time of ⁇ 1 second in the space above the catalyst bed.
• a device which is characterized by a ring manifold of a plurality of concentric, with outlet openings provided annular tubes above a Katalysator - bed, wherein the outlet openings are formed for discharging the oxygen in a deviating from the vertical oblique angle to the catalyst surface.
• the gas outlet openings may be formed as bores or nozzles.
• Fig. 1 is a greatly simplified representation of a device according to the invention and in
• Fig. 2 shows an enlarged detail as a sectional drawing of the ring distribution system for the oxygen entry and in the
• 3 and 4 are schematic diagrams of the flow direction of two streams of oxygen particles on the catalyst bed at different angles of incidence.
• Oxireaktor has a gas inlet tube 2, which passes through a horizontally arranged catalyst 3 centrally, wherein above the catalyst bed in the reactor, a gas 4 is formed.
• the central gas inlet tube 2 is surrounded by a ring manifold 5 for oxygen in pure form, as air or mixed with inert gas or water vapor, said annular tube 5 feeds a plurality of outlet tubes 6 equipped with annular tubes 7, which are arranged above the catalyst 3.
• the outlet openings 6 are arranged so that the respective oxygen jet impinges on the catalyst surface at an angle deviating from the vertical, wherein the vertical impact situation is shown in FIG. 3 and in FIG. 4 one of the situations according to the invention.
• the O z entry into the ring manifold 5 is indicated only by arrows 8, and the gas outlet of the reactor is only indicated and carries the reference numeral. 9
