| dc.description.abstract | In this work, a novel fixed-bed adsorption apparatus developed to carry out adsorption breakthrough curve experiments at cryogenic temperatures (between 195.15 and 273.15 K) and high pressures (up to 12 bar) was validated to screen candidate adsorbents for dynamic separation of H2 from natural gas grids. To validate the apparatus, breakthrough curve experiments of CH4 and H2, and their mixtures on binder-free zeolite 13X were performed. The equilibrium data obtained were fitted with the viral, dual-site Langmuir, and Langmuir isotherm models. Moreover, the equilibrium data and the isosteric heat of adsorption were compared with the data available in the literature obtained by microcalorimetric, gravimetric, and volumetric methods. Additionally, binary experiments were performed and simulated by using Aspen Adsorption to evaluate the deviation of ideality due to the extreme experimental conditions. | pt_PT |
