구리계 촉매를 이용한 VOC(벤젠)의 산화특성 = Oxidat ion Character ist ics of VOC(benzene) Using Copper Base Catalyst

다국어 초록 (Multilingual Abstract)

Oxidation characteristics of benzene as a VOC was investigated using a fixed bed reactor system over copper base catalysts. The copper base catalysts were made by using copper nitrate reagent and various support materials such as γ-Al₂O₃, TiO₂, and zeolite. The parametric tests were conducted at the reaction temperature range of 200～500℃, benzene concentration of 1,000～2,000 ppm, and space velocity range of 5,000～20,000 hr^-1. The property analyses such as BET, SEM, XRD and the conversions of catalytic oxidation of VOC were examined. XRD analysis on copper catalysts showed CuO crystal forms and the peak intensity of CuO increased as the impregnation weight of copper grew. The experimental results showed that the conversion was increased with decreasing space velocity. It was also found that Cu/γ-Al₂O₃+TiO₂ catalyst showed the highest activity for the oxidation of benzene and 15% metal loading was the optimum impregnation level.
