Abstract(s)

Green hydrogen (GH) is a hot topic in the shift to clean energy, holding a promise to meet global energy demand while contributing to climate action goals. Its transportation can be done into Natural Gas (NG) grids, being necessary a separation technology to provide pure GH and NG to the end user. Accordingly, in this work, a series of breakthrough experiments evaluated the performance of binder-free zeolite 13X as a potential adsorbent to purify GH blended into NG grids. Single and multicomponent experiments were performed at 195, 231, and 273 K and pressure up to 1800 kPa. Noteworthy, the material enables a thermodynamic-based separation of these components due to its strong interaction with CH4, resulting in selectivity values up to 17 at 195 K. The dual-site and standard Langmuir isotherm models fitted the adsorption equilibrium data, being the simulated multicomponent breakthrough curves suitably predicted by a homemade dynamic mathematical model.
