Synergistic material and process development: Application of a metal-organic framework, Cu-TDPAT, in single-cycle hydrogen purification and CO2 capture from synthesis gas

We employ a synergistic material and process development strategy to improve the performance of single-cycle vacuum pressure swing adsorption (VPSA) for hydrogen purification CO2 separation from reforming-based synthesis. Based on process-informed adsorbent selection criteria, including high cyclic capacity selective uptake impurities like CO, N2, CH4 over H2, metal organic framework (MOF), Cu-TDPAT, is selected. First, isotherms CO2, CH4, N2 H2 are measured. Subsequently, column model used optimization-based analysis VPSA cycle with Cu-TDPAT as assess both performance, in terms energy consumption productivity. The characteristics require an adaptation original increase process. After this adaptation, clearly outperforms benchmark material, zeolite 13X, several metrics higher purities recoveries fewer columns needed continuous Most importantly, offers two-fold improvement productivities when compared thus substantially decreasing bed size required achieve same throughput. However, 13X remains better reaching due its selectivity all other components gas stream, which leads overall lower consumption. obtained results show that final strongly depends interplay various factors related Hence, integrated design approach should be new paradigm developing novel processes.
