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).
