초록
산업발전과 공업화로 인해 VOCs의 발생이 증가하고 있고, VOCs는 불쾌감을 주며 불만을 불러일으키는 요인 중 하나이다. 이를 제어하기 위해 본 연구는 식물정유와 광촉매로 흡수제를 제조하여 벤젠과 톨루엔을 제거하고자 하였다. 식물정유물질 선정실험을 수행한 결과, 편백나무의 제거효율이 약 70%로 가장 높게 나타났으며, GC분석 결과 Monoterpene류와 Sesquiterpene로 이루어져 있음을 확인하였다. 광촉매 선정실험 결과, 광촉매 종류는 TiO2의 효율이 가장 높게 나타났으며, UV lamp power는 10 W, TiO2의 양은 0.1 g L-1부터 효율이 우수하게 나타났다. 수산화라디칼 생성특성 실험결과, TiO2의 농도와 UV lamp power가 클수록 많은 양의 라디칼이 생성되었다. 제조된 흡수제의 제거효율 및 반응속도 실험결과, 제거효율은 최대 약 98%까지 나타났으며, 활성화 에너지는 약 18 kJ mol-1로 나타났다.
Volatile organic compounds (VOCs) are widely used in both industrial and domestic activities. VOCs are one of the most unpleasant, frequently complaint-rousing factors of pollution around the world. It is now necessary to research and develop an alternative technology that could overcome the problems of the existing odor-control and VOC-eliminating techniques. In this study, essential oil and photocatalytic process was applied in the removal of benzene and toluene, typical VOCs in petrochemistry plant. therefore, this study conducted experiments on the selection of appropriate essential oil, photodegradation, hydroxyl radical generation capacity. The removal efficiency and reaction rate were performed to selecte the type and concentration of essential oil. As a result, removal efficiency of Hinoki Cypress oil was approximately 70% and reaction rate of Hinoki Cypress was high. The results of photolysis experiment, photocatalytic oxidation process showed that the decomposition efficiency of VOCs increased considerably with increasing UV lamp power. In addition, the conversion of VOCs was increased up to 0.1 g L-1 photocatalysts. The hydroxyl radicals measure was performed to determine the ability to generate hydroxyl radicals. The analytical result showed that high TiO2 concentration and lamp power was produced many hydroxyl radical. Experiments of the removal efficiency and reaction rate were performed using essential oil and photooxidation. As a result, the removal efficiency showed that the removal efficiency was increased high temperature and reaction time. The activation energy was calculated from the reaction rate equation at various temperature condition. Activation energy was approximately 18 kJ mol-1.
