Abstract
This paper presents the adsorption isotherm experiment of Methane and Maxsorb III activated carbon that was conducted and analyzed at temperatures from 5 to 55 degrees C and pressures up to 2.2 MPa in a volumetric apparatus. It is a complementary to the previous efforts by ways of analyzing the importance between charging and discharging rate, temperature increase and reduce of the bed, the heat transfer process, and the cylinder cooling and heating requirements during the charging and discharging of adsorbed natural gas.
