Abstract

A particle-based mathematical model is proposed. It contains a one-dimensional approximation of the flow with heat transfer in the chamber wall and the catalytic material. It is designed for packed bed reactors with spherical granulated catalytic materials and is customized for high-test peroxide as fluid. The unsteady flow in the cold start phase can be analyzed. The temperature values increase over the time and the mass fraction of the chemical components are useable for a better understanding of the process inside and a precise design of new catalytic chambers with an improved functionality.
