Compressed natural gas (CNG) is currently being utilized as one of the fuels for vehicles in Thailand. However, the CNG still has much lower energy density than other fuels such as gasoline or diesel. To improve the storage capacity of CNG, the use of an adsorbent that can adsorb natural gas is suggested. The purpose of this study is to determine the amount of methane adsorbed on Metal Organic Frameworks (MOFs); Basolite C300 and Basolite Z1200; and activated carbons derived from coconut shell and eucalyptus. The volumetric adsorption apparatus was used to determine the amount of methane adsorption. Methane was pressurized up to 900 psia, and the temperature was set at 303, 308, and 313 K. The adsorbents were also characterized for physical properties. The results show that the gravimetric amount of methane adsorption is highest when using Basolite C300, followed by Baolite Z1200, Eucalyptus Powder Activated Carbon, and Coconut Shell Powder Activated Carbon. The experimental data were best fitted by Sips isotherm model.
