3 Design or Simulation of a Fixed Bed Reactor for Catalytic Hydrocarbon Oxidation 

In this example the design or simulation of a multitubular reactor for a catalytic hydrocarbon oxidation is discussed [Froment, 1967]. The case considered here k of a rather complex nature, that is, 

This reaction model is fairly representative of the gas-phase air oxidation of o-xylene into phthalic anhydride on V2O5 catalysts A represents o-xylene, B phthalic anhydride, and C the final oxidation products CO and CO2 lumped together. The process conditions were already described in Section 11.5.2. The purpose of this example is mainly to check whether or not radial temperature 

Due to the very large excess of oxygen, the rate equations will be considered to be of the pseudo-first-order type, so that, at atmospheric pressure, 

A more detailed reaction scheme and more realistic kinetic model accounting for the interaction of the species with the catalyst and the reoxidation of the latter by the oxygen of the feed was derived by Papageorgiou and Froment [1995]. Its application is reported in Section 11.10.
