자동차 폐촉매를 이용한 휘발성유기화합물(VOC)의 제어기술 = Control Technology of VOC Using a Waste Automotive Catalysts

다국어 초록 (Multilingual Abstract)

The characteristics and the combustion activities of a waste automotive catalyst were carried out in this study. Methanol was selected as a model VOC(Volatile Organic Compound) and the combustion activity was examined in a fixed bed reactor. The characteristics of waste automotive catalyst was investigated by EA(Elemental Analysis). ICP-AES(Inductively Coupled Plasma-Atomic Emission Spectrophotometer) and BET(Brunauer-Emmett-Teller) analysis. Carbon deposit amount was decreased with increasing pretreatment temperature and air. Conversion of methanol at the reaction temperature of 100℃ was above 90% on the regenerated catalyst with air,60cc/min,400℃.1hr. The selectivities of HCHO and HCOOCH₃were decreased with increasing reaction temperatures. And combustion activity of a waste automotive catalyst was decreased with mileage. Catalytic activity of a waste automotive catalyst for methanol combustion was increased with acid treatment, and the order of acid effect was summarized as follows : HNO₃>HCL>H₂SO₄>CH₃COOH. Finally, we might say that the regenerated waste automotive catalyst by regeneration method has a excellent catalytic activity for VOC combustion.
