Abstract

The characteristics of desorption reaction and the heating values of used activated carbons collected from the companies of Shiwha/Banwal industrial complex were investigated. The desorption characteristics of used activated carbons were analyzed based on the data obtained from a thermogravimetric analyzer. The activation energies and reaction orders for desorption reaction of used activated carbons were calculated by employing Freeman-Carroll method. Heating values of volatile organic compounds(VOC) desorbed from used activated carbons were estimated based on the data obtained from a total hydrocarbon analyzer. It was found that the reaction orders of desorption of used activated carbons were 0.1~0.8, their desorption activation energies, 6.9~26.4 kJ/mol, and VOC heating values, 0.4~10.7 kcal/kg.

시화/반월 산단 내 활성탄 흡착탑을 사용하는 대표적인 업체에서 수거한 폐활성탄의 탈착특성 및 열량특성을 조사하였다. 열중량분석기를 이용하여 폐활성탄의 탈착반응특성을 조사하였다. 탈착특성 데이터를 바탕으로 탈착반응특성 비교에 중요한 요소인 반응차수 및 활성화에너지를 구하기 위하여 Freeman-Carroll법을 사용하여 반응차수와 활성화에너지 값을 구하였다. 또한 폐활성탄에 흡착되어 있는 휘발성 유기 화합물의 총탄화수소 배출특성을 이용하여 톨루엔을 기준으로 한 휘발성 유기 화합물의 열량을 계산하였다. 본 연구에서 는 반응차수가 0.1~0.8, 활성화에너지가 6.8~26.4 kJ/mol로 나타났으며, 열량은 업체별로 0.4~10.7 kcal/kg으로 나타났다.
