Volatile organic compounds (VOCs) are the typical pollutants
emittedfrom 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. So VOCs is themain problem in air pollution
prevention of petrochemical industry always.This study treated
Acrylonitrile (AN) by means of a commercialcatalyst, MnO/Fe2O3
in a fixed bed reactor. Researching into theeffects of operating
factors, activity decay, and kinetics ofcatalytic incineration.
Then pursuit for the best modify charactersof catalytic
oxidation from the experimental data.The effects of operating
factors, such as temperature,space velocity, AN concentration,
and oxygen concentration on the catalytic oxidation were
performed. We found that, it would get higherconversion of AN
for higher inlet temperature, and higher oxygen concentration
did also. The conversion of AN decreased with the increasing
concentration and decreasing space velocity. From the
statistical analysis of regression parameters that we found, the
parameter "temp" is the most effective factor on the catalytic
oxidation,and "oxygen concentration", "AN concentration", "space
velocity" effectedcatalytic oxidation in seriation.Besides, the
kinetics of catalytic oxidation of VOC has been made bythe
differential methods and several kinetic models such as power-
rate,Mars and Van Krevelen, Langmuir-Hinshelwood models have
been used toanalyze the results.The results of kinetics were
shown as follows: By the differentialmethod, the kinetics of
catalytic incineration of acrylonitrile wassuitable for the Mars
and Van Krevelen model, and its reduced activationenergy was 2.9
KJ/mole, and its oxidant activation energy was 9.8 KJ/mole.
