Abstract

A catalyst charge for ammonia oxidation, including the Andrussow process, comprises a first stage ammonia oxidation catalyst capable of oxidising 20 to 99% of designed ammonia throughput, to produce a first stage product gas comprising unreacted ammonia, oxygen and nitrogen oxides, and a second stage ammonia oxidation catalyst capable of completing the oxidation of unreacted ammonia. In its preferred embodiments, low levels of nitrous oxide are produced and extended campaign lengths may be seen. Improved performance on start-up is another benefit.
