Definitions
- the invention relates to a method and a device for reducing nitrous oxide, which is formed in the catalytic combustion of ammonia and oxygen to nitrogen oxides, a catalyst system consisting of at least a first catalyst network and at least a second catalyst network for the catalytic combustion of ammonia and oxygen to nitrogen oxides is used and wherein at least a first catalyst network is a platinum rhodium network.
- nitrous oxide (laughing gas), which is suspected of destroying the terrestrial ozone layer, is formed in the process of degrading it his. It is therefore extremely important in the production of nitric acid to subsequently effectively destroy the N 2 O produced or to largely avoid the formation of the nitrous oxide.
- the yield of desired nitrogen oxides should not be impaired here.
- DE 198 19 882 A1 discloses a process for the catalytic decomposition of N 2 O in a gas mixture obtained in the production of nitric acid by catalytic oxidation of ammonia over a catalyst for the decomposition of N 2 O, which is characterized in that the resulting from the Catalytic oxidation of ammonia obtained hot gas mixture is contacted with a catalyst for the decomposition of N 2 O before subsequent cooling.
- DE-OS 22 39 514 discloses an arrangement of catalyst gauzes for accelerating a reaction between two or more gases flowing through the gauze, which is characterized in that a gauze group flow directed downward on the side pe made of precious metallic material is arranged on a second gauze group made of non-precious metallic material and less easily evaporating metallic material that can be removed by the gases, which supports the acceleration of the reaction during operation.
- DE-OS 19 59 137 discloses a catalyst with a platinum and rhodium content of from 12 to 20% by weight for the oxidation of ammonia to nitrogen oxide.
- EP 0 359 286 B1 discloses a process for reducing nitrous oxide, which is formed in the catalytic combustion of ammonia and oxygen to give nitrogen oxides and then cooled in a heat recovery unit and absorbed in water and / or dilute nitric acid, which is characterized in that the warm combustion gases are given a retention time of 0.1 to 3 seconds before they are cooled. This makes it possible to decompose up to 90% of the N 2 O formed.
- EP 0 611 041 B1 discloses a method for attenuating the N 2 O emissions during the start-up phase of an ammonia oxidation reaction, using a platinum-based catalyst mesh and including a platinum trap mesh comprising fibers of a palladium alloy, the palladium alloy 0.1 to 5 Contains% by weight cobalt.
- DE 198 05 202 A1 describes a process for the production of nitric acid in which ammonia is burned on at least one catalyst network, in particular platinum network, with the supply of oxygen and the reaction gases are cooled, the reaction gases downstream of the catalyst network being cooled via a temperature-stable one Catalyst for the conversion of the N 2 O contained in the reaction gases are performed.
- ammonia is mixed with oxygen and at a temperature of approx. 860 ° C. by passing a first catalyst mesh, which is a platinum rhodium mesh with typically 5.0 to 10.0% by weight rhodium , and burned by passing a second catalyst network, this second a palladium-rhodium network with at least 92% by weight (or more) of palladium, 2 to 4% by weight of rhodium, the rest of platinum or alternatively with 82 to 83% by weight of palladium, 2 , 5 to 3.5% by weight of rhodium, the rest is platinum, and thereby achieves a highly efficient reduction of the nitrous oxide content.
- a gas-permeable structure is referred to as a mesh, which is essentially metallic and is produced, for example, by knitting, knitting, weaving or fleece laying.
- the palladium-rhodium network has a rhodium content of 2.5 to 3% by weight) and a palladium content of 82.5% by weight, since this enables particularly low N 2 O formation to be achieved.
- the palladium-rhodium mesh is spaced from the platinum-rhodium mesh by means of at least a third mesh in order to avoid welding of the different mesh types, the heat-resistant steel (FeCrAI alloy, e.g. megapyr or Kanthai) has proven itself.
- FeCrAI alloy e.g. megapyr or Kanthai
- the palladium-rhodium network can contain at least one further metal from the group consisting of iridium, ruthenium, rhenium, cobalt, nickel, copper, and gold to increase the mechanical stability of the palladium rhodium catalyst networks while maintaining the catalytic function.
