Abstract
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).
Claims7
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.
