Simulation d'un réacteur catalytique à lit fixe (Oxydation du propène)

Abstract

A bidimensional pseudo homogeneous model is developed to explain the behaviour of a fixed bed catalytic reactor for oxydation of propene to acrolein. The rate of the main reaction and of side reaction are expressed as power fonctions of partial pressures of oxygene and propene. Heat transfer parameter (Pe,,, et Bi) necessary for simulation are obtained by the help of temperature profiles in the absence of reaction. The integration of the model has been done by orthogonal collocation and the results i.e. temperature profiles and outlet Concentration are compared with experimental data.
