Investigations of catalytic incineration of ethylene oxide (ETO) over Pt/Al2O3 catalyst have been conducted on laboratory and pilot scale level. The measurements of the reaction rate conducted under gradientless conditions have been used to evaluate kinetics parameters valuable for reactor modeling. A reactor model is proposed which could a priori predict behavior of catalytic convertor under various operating conditions (inlet temperature, inlet pollutant concentration and space velocity) based on the kinetics parameters and mass and energy balances. The results show satisfactory agreement between predicted and experimental values of conversion and temperature profiles along the catalyst bed. (c) 2005 Elsevier B.V. All rights reserved.
