| titleOfInvention | Method for oxidising ammonia and system suitable therefor |
| abstract | The present invention relates to a method of oxidizing ammonia with oxygen in the presence of a catalyst containing at least one transition metal oxide that is not an oxide of a platinum metal. The ratio of the molar amount of oxygen and ammonia upon entry into the catalyst bed of the reaction gas mixture is set to a value of 1.75 mol O 2 / mol NH 3 or less. The invention also relates to an ammonia oxidation system comprising the following components: A) Reactor 3 for ammonia oxidation with at least one supply line for a reaction gas mixture and at least one discharge line for a process gas. , B) a catalyst (3c) containing at least one transition metal oxide other than an oxide of platinum metal inside the reactor (3), c) a selected amount of oxygen-containing gas flow having an O 2 content of less than 20% by volume A device for setting the molar ratio of oxygen to ammonia in the reaction gas mixture to 1.75 mol / mol or less by mixing with ammonia, wherein the oxygen-containing gas flow is c1) the air flow is less than 20 vol%, preferably 10 vol% By means for diluting with a gas flow containing less than, particularly preferably less than 5% by volume, or c2) oxygen from the oxygen-containing gas mixture, preferably It is by a device for exhaustion of the air, or c3) device produced by the combination of means for c1 and c2. The oxidation system of ammonia can be included as a production system for nitric acid or caprolactam. The method and system are characterized by the use of high productivity, long life and low cost catalysts. |
