Characteristics of VOC(benzene) treatment were investigated using a fixed bed reactor system over copper base catalyst and photocatalyst/adsorbent blending material. The copper base catalysts were made by using copper nitrate reagent and various support materials such as γ-Al₂O₃, TiO₂. The parametric tests were conducted at the reaction temperature range of 200~400℃, benzene concentration of1,000~2,000 ppm, and space velocity range of 5,000~10,000 hr<sup>-1</sup>. The property analyses such as BET, SEM and the removal efficiency(conversion) of VOC were examined. The experimental results showed that the VOC removal efficiency of hybrid method was higher than that of single method. It was also found that the comprehensive feasibility study of hybrid method would need with considering various factors including additional expenses.

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.

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<sup>-1</sup>. 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.

Absorption of H₂S and physicochemical properties of charcoal was investigated using various charcoals such as hard charcoal, fine charcoal made of bamboo, and charcoal made of bamboo. The properties of various charcoal were analyzed using BET, SEM and pH meter and absorption experiment for H₂S was carried out to determine the absorption equilibrium in the batch reactor. As results of analysis for properties, the pHs were arranged in order of hard charcoal > charcoal made of bamboo > fine charcoal made of bamboo. The pH of original sample was the highest and pH of desorption sample was lower than that of absorption sample. It was also found that adsorption equilibriums of fine charcoal made of bamboo and charcoal made of bamboo were higher than hard charcoal. Therefore, fine charcoal made of bamboo and charcoal made of bamboo can be applied more efficiently than hard charcoal to remove the odor such as H₂S by adsorption in the atmosphere at the normal temperature.

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<sup>-1</sup>. 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.

산업의 발전과 경제규모의 팽창에 따라 에너지소비가 크게 증가되는 가운데 대기오염물질배출이 크게 늘어 나면서 심각한 환경문제를 야기하고 있다. 이중에서 황화수소(H<sub>2</sub>S)는 계란 썩는 냄새가 나는 무색의 유독한 기체로서 인체의 위장이나 폐에 흡수되어 질식, 폐 질환, 신경중추마비 등을 발생시키고 있다. H<sub>2</sub>S 가스는 폐기물매립장, 석유 정제업, 펄프공업, 도시가스 제조업, 암모니아공업, 하수처리장 등 다양한 곳에서 발생하고 있으며, 이를 처리하기 위하여 심냉법, 흡수법, 막분리법, 흡착법 등 여러 가지 처리방법이 제시되었다. 본 연구에서는 실험실규모의 장치를 이용하여 바이오매스 부산물을 활용한 악취저감용 흡착소재개발을 위해 밤껍질을 대상으로 탄화, 스팀활성처리등의 과정을 거쳐 흡착제를 제조하였으며, BET분석, SEM등을 이용한 물성분석, 회분식의 흡착평형실험, 악취 모니터링실험을 통한 흡착특성을 고찰하였다. 실험결과, 밤껍질을 활용하여 탄화 및 활성처리과정을 거치면서 얻을 수 있는 흡착제의 수율은 15∼20%에 해당되는 것으로 밝혀졌다. 또한, 밤껍질부산물은 스팀을 이용한 활성처리 과정에서 온도가 증가할수록. 시간이 증가할수록 스팀-탄소 화학 반응에 의해 내부기공이 커지면서 비표면적이 증가되는 것으로 밝혀졌다. 아울러, 밤껍질부산물을 소재로한 흡착제의 황화수소 평형흡착능과 파과성능은 활성탄대비 비교적 우수한 성능을 보임으로써, 악취제거용 흡착소재로 활용성이 클 것으로 예상되었다.
