- Abstract
Equilibrium data for carbon dioxide and methane adsorption on nanoporous metal organic framework Cu-BTC powder and tablets were measured in a magnetic suspension balance in the temperature range of 308-373 K and a pressure range of 0-7 bar and fitted with Langmuir model. The tablets adsorption loading is 0.63 mol kg-1 for methane and 3.1 mol kg-1 for carbon dioxide at 1 bar and 308 K, while these values are 0.77 and 3.9 mol kg-1 for powder in the same conditions. Isosteric heats of adsorption were 22.8 and 15.0 kJ mol-1 for carbon dioxide and methane, respectively, on both adsorbents, which indicates a strong adsorption of carbon dioxide. Also, single and binary breakthrough curves were measured in the same temperature range and atmospheric pressure by using Cu-BTC tablets as adsorbent. A complete model was used in the simulation of breakthrough curves and good agreement was observed with experimental data.
