Environmental laws limit and press the industries to control the emission of Volatile Organic Compounds (VOC) around the world. Total catalytic oxidation is a suitable technology for removing and control of VOC in industries, but poisons, like Organic Silica Compounds, deactivate these catalysts. In this paper, this problem is investigated over Pt/g-Al2O3 catalyst with emphasis on Organic Silica Compounds as poison. The effect of catalyst carrier has been investigated and the reversibility phenomenon has been researched in this poisoning process too.
