Adsorption equilibrium isotherms of hydrogen and methane are reported for the temperature range 303-333 K and pressure up to 4 MPa. The adsorbent was 5A molecular sieve (supplied by Rhone Poulenc industries Ltd.). Experimental data were obtained using a static system for gas-solid adsorption. The Langmuir adsorption equilibrium equation gave excellent predictions. Adsorption of hydrogen and methane on 5A molecular sieve is purely physical since the isosteric heat of adsorption was found to be equal to 9.889 and 14.804 kJ mole-1 for hydrogen and methane, respectively.
