Adsorption equilibria of methane, ethane, ethylene, nitrogen, and hydrogen onto activated carbon

Adsorption equilibria of single components for pure methane, ethane, ethylene, hydrogen, and nitrogen onto activated carbon adsorbent (Calgon Co.) were measured. The results were obtained with a static volumetric method at 293.15 K, 303.15 K, and 313.15 K and at pressures up to 2 MPa. Experimental data were correlated by the Langmuir-Freundlich equation. Isosteric enthalpies of adsorption were calculated and shown according to surface loading.
