Abstract
In the industrial production of nitric acid by the oxidation of ammonia over rhodium-platinum gauze catalysts the infrequent occurrence of an inactive gauze has prompted a number of investigations into their behaviour. This paper reports on a survey of the surface structure of individual gauzes in a catalyst pack and offers some indications towards the choice of optimum process variables.
