Abstract The gradual separation of the naphtha steam cracking product (propane/propylene/ethylene, C 3 H 8 /C 6 2 4 ) to obtain highly pure is great significance as it provides an alternative process for this important industrial feedstock. However, developing adsorbents meet efficient and purification application remains challenging. A water coordination‐decorated metal–organic framework (MOF, Cd‐dtzip‐H O) material reported. Interestingly, molecules cooperate with build a vortex significantly affect preferential adsorption . At 298 K 100 kPa, loading in 112.0 cm g −1 , equivalent 1.7 2.0 times respectively. Experimental breakthroughs show that efficiently separates under different pressures. Meanwhile, also unprecedentedly achieves one‐step mixtures yielding high‐purity (99.9%) (99.95%) products productivities 38.2 12.7 L kg

High‐Capacity Volumetric Methane Storage in Hyper‐Cross‐Linked Porous Polymers via Flexibility Engineering of Building Units

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 12, 2025

Abstract Adsorbed natural gas (ANG) storage is emerging as a promising alternative to traditional compressed and liquefied methods. However, its onboard application restricted by low volumetric methane capacity. Flexible porous adsorbents offer potential solution, their dense structures unique gate‐opening effects are well‐suited enhance capacity under high pressures. This study developes series of hyper‐cross‐linked polymers (HCPs) with tunable flexibility modifying the aliphatic chain length in double‐benzene‐ring building blocks, employing cost‐effective external crosslinking approach. The resulting flexible polymer, HCP‐DPP, exhibits pore expansion specific pressures, producing high‐pressure adsorption isotherm behavior. Combined intrinsic skeleton, this feature leads superior performance over rigid counterparts. Notably, HCP‐DPP achieves record‐high total uptake 333 cm 3 STP −3 working 291 at 273 K 100 bar, exceeding U.S. Department Energy (DOE) target 263 . These findings lay foundation for developing advanced practical ANG applications.
