복합담체의 전이금속촉매를 이용한 VOC(벤젠)의 산화특성 연구 = Oxidation Characteristics of VOC(benzene)Using Transition Metal Catalyst with Composite Supports

다국어 초록 (Multilingual Abstract)

Oxidation characteristics of benzene as a VOC were investigated using a fixed bed reactor system over transition metal catalysts. The transition metal catalysts were made by using transition metal nitrate reagent and various support materials such as γ-Al₂O₃, and TiO₂. The parametric tests were conducted at the reaction temperature range of 200～500℃, benzene concentration of 2,000～3,000 ppm with space velocity of 10000 hr^-1. The property analyses such as BET, SEM, TGA and the conversions of catalytic oxidation of VOC were examined. The experimental results showed that the BET surface areas of catalyst are 86.4∼167.7㎡/g, the pore volumes are 0.049∼0.056㎤/g, and the average pore sizes of catalyst are 27∼44Å which mean the meso pore. It was also found that the conversion of benzene oxidation reaction at 400∼500℃ with Cu/γ-Al₂O₃+TiO₂ catalyst showed 90∼100%, which indicate that the transition metal catalyst with composite supports is very effective for the oxidation of benzene.
