Comparison of Ethylene Adsorption onto Activated Carbon Cloth and Granulated Activated Carbon in Dynamic Phase

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