Volatile organic compounds (VOCs) are the typical pollutants
emitted from the petrochemical industrial processing. They are
high radicals , react with some chemical compounds like Nox ,
Ozone in the atmosphere , and photochemical smog , carcinogen
are formed also. Hence, VOCs are the main problem in air
pollution prevention of petrochemical industry always.This study
treated Styrene (SM) by means of a commercial catalyst, MnO/Fe2
O3 in a fixed bed reactor. It can be classfied into three major
parts. 1. We investigate the effects of operating factors,such
as temperature,VOC concentration,space velocity and O2
concentration on the performance of the catalyst.2. A couple of
life-tests of the catalyst were carried out to characterize the
effect of Styrene（SM）poisoning.3. Three kinetic models,such as
power-rate law,Mars and van Krevelen model and Langmuir-
Hinshelwood model were used to fit the kinetic data of the
incineration of Styrene（SM）.We found that,from the
experimental results, it would get higher conversion of SM for
higher inlet temperature, and higher oxygen concentration did
also. The conversion of SM decrease with the increasing VOC
concentration and space velocity. From the statistical analysis
of regression parameters,we found that the parameter "temp" is
the most effective factor on the catalytic oxidation, and
"oxygen concentration", "SM concentration", "space velocity"
effectivity catalytic oxidation in seriation.The results of
kinetics were shown as follows: By the differential method, the
kinetic of catalytic incineration of Styrene is suitable for the
Langmuir-Hinshelwood model, and its Activation Energy are 27.968
KJ/mole（Molcular Oxygen adsorbed） and 29.151 KJ/mole（Atomic
Oxygen adsorbed）at low temperature.Its activation energy，at
high temperature，are 16.439 KJ/mole（Molcular Oxygen adsorbed）
and 16.050 KJ/mole（Atomic Oxygen adsorbed）.
