Abstract

The powder recovered from the catalyst and catchment systems in a high pressure ammonia oxidation plant has been studied by a variety of analytical means. From this investigation it can be concluded that the powder results from the in-depth degradation of the platinum-rhodium catalyst gauzes and the palladium-copper catchment gauzes, together with impurities arising from the reactor constructional materials. The results indicate two different transport mechanisms, and the study may assist in the development of more stable platinum-based catalysts and catchment packages for nitric acid plants.
