摘要：A process for the oxidation of ammonia, including the Andrussow process is described, wherein a mixture comprising air and ammonia is contacted with a precious metal ammonia oxidation catalyst and the resultant gas mixture contacted with a catalyst effective for the decomposition of nitrous oxide, characterid in that prior to contacting the gas mixture with the catalyst effective for the decomposition of nitrous oxide, the gas mixture is contacted with a guard material. The guard material protects the nitrous oxide decomposition catalyst from deposition of precious metal and/or catalyst poisoning. In a preferred embodiment the catalyst effective for the decomposition of nitrous oxide also functions as an ammonia oxidation catalyst.
