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.
