Abstract

Desorption reaction characteristics of the used activated carbons collected from painting process in Shiwha/Banwal industrial complex were investigated. Thermogravimetric analyzer was used to investigate the desorption characteristics. Activation energies and reaction orders for desorption reaction characteristics of used activated carbons were estimated by employing Friedman method and Freeman-Carroll method. In the used activated carbons collected from painting process, it was found that the activation energies were 20.6~43.2 kJ/mol in Friedman method and 12.3~26.5 kJ/mol in Freeman-carroll method, and reaction orders were 0.1~1.7.

시화/반월 산단 내에서 활성탄 흡착탑을 사용하는 업종 중 도장 공정을 사용하는 대표적인 업체에서 수거한 폐활성탄의 탈착특성을 조사하였다. 탈착특성을 조사하기 위하여 열중량분석기(Thermogravimetric Analyzer)를 사용하였다. 탈착특성 자료를 바탕으로 탈착 특성비교에 중요한 요소인 반응차수와 활성화에너지를 구하기 위하여 Friedman법과 Freeman-carroll법을 사용하였다. 도장 공정에서 수거한 폐활성탄으로 Friedman법을 이용하여 활성화에너지를 계산한 결과 20.6~43.2 kJ/mol을 나타내었으며, Freeman-Carroll법을 이용하여 활성화에너지와 반응 차수를 계산한 결과 활성화에너지는 12.3~26.5 kJ/mol, 반응 차수는 0.1~1.7을 나타내었다.
