Mn/γ-Al₂O₃ 촉매의 VOC(벤젠) 산화반응특성

Benzene Oxidation Characteristics of Mn/γ-Al₂O₃ Catalyst

Catalytic oxidation characteristics of benzene(one of important compound of volatile organic compounds : VOCs) was investigated in a flxed bed flow reactor using Mn/γ-Al₂O₃ catalyst. As operating variables for the experiment, reaction temperature(200~500℃), benzene concentration(1,OOO~3,000ppm), space velocity (5,000~60,000hr^-1) were applied. The experimental results showed that the conversion of catalytic oxidation of benzene increased with decreasing space velocity, while decreased with increasing inlet VOCs concentration. The catalytic oxidation reaction for Benzene could be expressed as the first order homogeneous reaction of which the activation energy was 9.2kcal/mol.
