Catalytic incineration is one of the cost-effective technologies to deal wi
th unwanted volatile organic compounds (VOCs). Catalytic incineration of st
yrene over a MnO/Fe2O3 catalyst was carried out in a bench scale catalytic
incinerator. Three kinetic models, the power-rate law, the Mars and van Kre
velen model and the Langmuir-Hinshelwood model were used to analyze the res
ults. A differential reactor design was used for best fit of kinetic models
in this study. The results show that the Langmuir-Hinshelwood model may be
feasible to describe the catalytic incineration of styrene. This suggests
that the chemical adsorption of either O-2 molecules or O atoms is importan
t in the process of catalytic incineration of styrene. (C) 2001 Elsevier Sc
