Estimation of platinum gauzes catalyst for ammonia oxidation in nitric acid production

Abstract

This paper illustrates design aspects of a shallow bed reactor involving a very rapid reaction, which is a diffusion controlled reaction. The design of the bed composed of a small number of catalyst screens, is normally based on past experience, scaleup on the basis of equal velocity, and careful planning for good distribution. Methods needed to estimate the number of meshes, diameter, height and volume of catalyst bed are discussed. This design method can be useful for economic or operating studies.
