Introduction and Aims: Ethylbenzene is one of the most important volatile organic compounds and one of 189 hazardous air pollutants that found in many indoor and outdoor environments and always creates air pollution concerns. Thus, before being discharged to the environment, it must be treated from polluted airstream. The aim of this study was the effect of combined use of ozone and carbosieve in the catalytic removal of ethylbenzene from the polluted airstream.
Materials & Methods: The study was experimental in which a combination of ozone and carbosieve as a catalys was used in the removal of ethylbenzene from the polluted airstream. The experiments were carried out in a reactor with the continuous system and the results of catalytic ozonation were compared with the results of single ozonation and carbosieve adsorbent. The sampling and analyzing were done with 1501 NMAM method by GC equipped with FID detector.
Results: The results of this study showed that the removal effectiveness of single ozonation process is averagely less than 25%. Also, the efficiency of absorbent decreased with the concentration increase of ethylbenzene.The increase ratio of  the efficiency in catalytic ozonation process to efficiency of carbosieve adsorbent was averagely 45%.
Conclusion: With regard to high efficiency of catalytic ozonation process and increasing the removal ethylbenzene, the catalytic ozonation process is suggested as a promising and alternative technology for the elimination of VOCs from the polluted air stream.
