Effect of Temperature on Methane Adsorption by Granular Activated Carbon

An experimental study was performed to determine the amount of methane adsorption by various granular activated carbon (GAC) at temperatures of 15, 25 and 35 ̊C. To carry out the experiments, a volumetric method was used up to pressure of 800 Psia. The methane adsorption capacity ofthree different granular activated carbon has been measured and the adsorption isotherm of each adsorbent has been provided at different temperatures. Also the adsorption isotherms of three different activated carbon are compared at constant temperature. The results showed that theamount of adsorption of GAC1 higher than GAC2 and GAC3 because of its high BET surface area. It is worth nothing that by increasing temperature, the amount of methane adsorption was decreased for three granular activated carbon used in this work
