Absorption characteristics of acetaldehyde(one of odors) were investigated using a bubble tank. The capacity of reaction tank made of acrylic is 1 liter and the experiment was carried out as semi-batch mode(for given absorbent packing, acetaldehyde was fed continuously with flow rate of 2liter/min). As operating variables of experiment, concentration of acetaldehyde(40~100ppm), absorption temperature(25~45℃), and packing volume of absorbent(100~300ml) were applied. The experimental results showed that the removal efficiency of acetaldehyde decreased with increasing concentration of acetaldehyde and absorption temperature, while it increased with increasing packing volume of absorbent.

r-Al₂0₃에 몰리브덴을 담지시킨 촉매를 고정층 반응기에 충전하여 벤젠과 같은 VOCs 의 촉매산화반응 특성을 살펴보았다. 실험조건은 반응온도를 200~500℃ 로 하고, 반응물인 벤젠의 농도를 1,000~3,000ppm, 공간속도를 5,000~60,000hr<sup>-1</sup> 의 범위에서 적용하였다. 연구결과, 벤젠의 전환율은 공간속도가 낮을수록 증가하고, 초기유입농도가 증가할수록 감소하는 것으로 나타났다. 몰리브덴이 담지된 촉매의 성능은 니켈을 제외한 구리나 망간등의 다른 전이 금속에 대해서는 다소 떨어지는 것으로 나타났다. 벤젠의 촉매연소반응은 1차 균일반응으로 해석 될 수 있었으며, 균일연소반응의 활성화 에너지값은 7.4kcal/mol 이었다. Catalytic oxidation characteristics of benzene(one of important source of volatile organic compounds : VOCs) was investigated in a fixed bed flow reactor using Mo/r-Al₂0₃ catalyst. As operating variables of experiment. reaction temperature(2OO-500℃), benzene concentration(1,000~3,000ppm). space velocity(5,000~60,000hr<sup>-1</sup>) were applied. The experimental results showed that the conversion of catalytic oxidation of benzene was increased with decreasing space velocity. while it was decreased with increasing inlet VOCs concentration. Mo/r-Al₂0₃ catalyst exhibited more or less low activity among several transition metals such as Cu. Mn. Cr. etc. except Ni. The catalytic oxidation reaction for VOCs(benzene) could be expressed as the first order homogeneous reaction the activation energy of which was 7.4kcal/mol.

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<sup>-1</sup>) 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.
