COMPARISON OF ETHYLENE ADSORPTION ONTO ACTIVATED CARBON CLOTH AND GRANULATED ACTIVATED CARBON IN DYNAMIC PHASE

Abstract

In this study, ethylene gas adsorption onto activated carbon cloth ACC and granulated activatedcarbon GAC were compared in dynamic phase using a home-built apparatus. ACC or GAC wereplaced into filter holder and a constant concentration of ethylene gas was introduced throughout ACfilter at a constant flow. From the gas flow just after the AC filter a certain amount of gas was takenby an injector and analyzed using gas chromatography to determine the amount of decrease inethylene gas concentration. It was found that ethylene gas adsorption capacity of ACC was 8.33 foldgreater than that of GAC
