Modelling adsorption based on an isoreticular <scp>MOF</scp> ?series of <scp>IFPs</scp> —Part <scp>II</scp> : Dynamic adsorption in fixed beds

Based on experimental pure component data for the characterization of isostructural imidazolate framework Potsdam (IFP) series reported in Part I, a model simulation non-isothermal dynamic adsorption CO2/CH4-mixtures fixed-bed columns is presented this II. The robustness examined and validated, by comparison to breakthrough at different process conditions, such as varying concentration, temperature, pressure. Thereby, predictive methods estimation equilibria mixtures are compared (RAST, IAST, ML). results show that ideal behaviour can be assumed with good accuracy system under consideration, except IFP-2, which shows significant deviations increased pressures temperatures. A detailed kinetic analysis reveals mass transfer significantly influenced micropore diffusion. Thus, only IFP-1 separation CO2 CH4 equilibrium-driven, while remaining IFPs regime dominates process, some cases increases efficiency (IFP-2 -7) but also inhibit it (IFP-8). determined intracrystalline diffusion coefficients very agreement values metal organic (MOF) compounds similar structure literature.
