Abstract (EN): In this work, two industrial dual-step pressure swingadsorption(PSA) processes were designed and simulated to obtain high-puritymethane, CO2, and syngas from a gas effluent of a CO2 electroreduction reactor using different design configurations.Among the set of zeolites that was investigated using Monte Carloand molecular dynamics simulations, NaX and MFI were the ones selected.The dual-PSA process for case study 1 is only capable of achievinga 90.5% methane purity with a 95.2% recovery. As for case study 2,methane is obtained with a 97.5% purity and 95.3% recovery. Both casestudies can produce CO2 with high purity and recovery (>97and 95%, respectively) and syngas with a H-2/CO ratio above4. Although case study 2 allows methane to be used as domestic gas,a much higher value for its energy consumption is observed comparedto case study 1 (64.9 vs 29.8 W h mol(CH4) (-1)).
