시화/반월 산단내 화학제품 제조업종에서 수거한 폐활성탄의 탈착특성 연구
Abstract
Desorption characteristics of waste activated carbons collected from chemicals manufacturing industries in Shiwha/Banwal industrial complex were investigated. Activated carbons were decomposed in a thermogravimetric analyzer (TGA) at 513K with heating rate of 10 ℃/min under nitrogen atmosphere. Activation energies and reaction orders for desorption, from the waste activated carbon were estimated by employing Friedman method and Freeman-Carroll method. It was found that the reaction orders of desorption in waste activated carbons were 0.27-1.69, and activation energies were 15.2-45.7 kJ/mol in Friedman method and 13.7-17.1 kJ/mol in Freeman-Carroll method.
