The invention relates to a method and device for the injection of oxygen in a reformer reactor, for example, for oxydehydrogenation, with an essentially radial throughflow of the gas mixture through a catalytic packing, whereby the incorporation and mixing of the oxygen before entry into the catalyst is significantly improved, in particular for oxydehydrogenation methods. The above is achieved, whereby the oxygen is introduced in pure form, as air, or mixed with inert gas, or with steam, into an annular distribution system (5) and injected out of a number of outlet openings (6) in the annular distribution system, at an angle to the perpendicular, onto the catalyst surface (3).

The invention claimed is: 1. Method for nozzle jetting of oxygen into a synthesis reactor for oxi-dehydration, with mainly radial flow of a gas mixture through a catalyzer packing, wherein oxygen is added to a ring distributor system in pure form, as air or mixed with inert gas or water vapor, and is then jetted from the ring distributor system directly to the catalyzer surface at an angle to the vertical through several exit openings in the ring distributor system, wherein the oxygen and the gas mixture first begin mixing immediately preceding entry to the catalyzer packing, after the oxygen is jetted from the ring distributor system, and wherein the nozzle jetting of the oxygen is carried out from the cylindrical plane in the interior of the catalyzer bed in the direction towards the reactor wall. 2. Method as claimed in claim 1, wherein the nozzle jetting is carried out with the help of several parallel pipes having exit openings and forming a cylindrical inner axial plane. 3. Method as claimed in claim 1, wherein the nozzle jetting of the oxygen takes place in a cylindrical axial plane approx. 50 to 300 mm before the cylindrical inner wall of the catalyzer bed, which ensures an oxygen dwelling time of ≦1 sec. in a chamber before the catalyzer bed. 4. Device for nozzle-jetting of oxygen into a synthesis reactor for oxi-dehydration with mainly radial flow of the gas mixture to a catalyzer packing, particularly for conducting a method as claimed in claim 1, wherein there is a ring distributor with several pipes with exit openings, wherein the several pipes together form an inner cylindrical plane before the cylindrical inner surface of the catalyzer bed, whereby the exit openings are aligned to release the oxygen on to the cylindrical catalyzer surface at an angle to the vertical. 5. Device as claimed in claim 4, wherein the gas exit openings are aligned in alternating sequence to adjacent exit openings of an adjacent ring pipe. 6. Device as claimed in claim 4, wherein adjacent exit gas openings reveal different flow exit directions. 7. Device as claimed in claim 4, wherein the gas exit openings are designed as holes or nozzles.
