ABSTRACT: The efficient production of ultrahigh-purity C2H4 and CH4, which are vital feedstocks for industrial processes and alternative energy, is increasingly in demand but remains challenging. Cryogenic distillation has been widely utilized for this purpose; however, it imposes a substantial energy burden. Herein, we report four robust porous polymer networks (PPNs), namely, PPN-35, PPN-45, PPN-55, and PPN-65, for the purification of C2H4 from C2H6/C2H4 mixtures and CH4 from C3H8/C2H6/CH4 mixtures. PPN-35, PPN-45, PPN-55, and PPN-65 exhibit IAST selectivities of 1.67, 1.43, 1.24,
