Reactor for catalytically oxidizing ammonia to nitrogen oxides

摘要

Reactor for catalytically oxidizing ammonia to nitrogen oxides contains a catalyst for decomposing N2O arranged between a precious metal lattice catalyst and a heat exchanger. Independent claims are also included for: (A) an apparatus for the production of nitric acid from ammonia comprising a reactor for catalytically oxidizing ammonia to nitrogen oxides containing a catalyst for decomposing N2O arranged between a precious metal lattice catalyst and a heat exchanger, and an absorber for nitrogen oxides, and a reducer for reducing nitrogen oxides; and (B) a process for catalytically decomposing N2O comprising contacting a hot gas mixture produced from the catalytically oxidation of ammonia with the catalyst for decomposing N2O before subsequent cooling.
