The ammonia oxidation reaction modifies the surface structure of the platinum based catalyst gauzes. Since some reaction paths of the process are known to be structure-sensitive it is of high importance to perefctly understand underlying dynamics. We can help you to better understand your process.

During operation the platinum based gauze catalysts undergo a massive reconstruction of their surface morphology accompanied by metal and activity losses.
The analysis of the used gauzes reveals what happened during operation and enables Umicore to determine the optimum balance between catalyst performance and requirements of the individual operating conditions of a particular plant.

This year’s newsletters regarding nitric acid and hydrogen cyanide manufacturing will all deal with questions around the topic of catalyst gauzes and their specifics during catalytic ammonia oxidation, such as optimisation of efficiency, structure and material, recrystallisation and PGM losses. Today we start with explanations on the Ostwald Process.
