β¦ Synopsis
Absfract-The kmetlcs of the catalytic au-oxldatlon of o-xylene to phthahc anhydrIde over various commercial V,O, and T10rV205 catalysts are extended and a model derived which correctly predicts the temperature and yield profiles m a quasi-Isothermal fixed-bed reactor of commercial dlmenslons The model predicts the relative freedom from thermal "run-away" of commercial fixed-bed reactors and IS used to demonstrate the possrtuhtles of operation at elevated Xylene concentrations In what follows, XH, TA, PI and PA refer to o-xylene o-toluakdehyde, phthahde and phthabc anhydrlde respechvely, sometimes abbreviated to A, B, C and D

The klnetlc parameters In a complex reaction network (oxldatlon of o-xylene over V205) were derived by multlresponse analysis of rate data from a tube-wall-catalytic reactor using two different catalysts The 2D model of thrs reactor was reduced to 1-D format by a systematic method of analysis which
The influences of "in-pore" diffusion and film heat and mass transfer on catalyst effectiveness and selectivity are examined for a system of highly exothermic parallel and consecutive reactions, typified, for example, by the partial oxidation of o-oxylene to phthalic anhydride.
