Purifying methane from natural gas using adsorbents not only requires the to possess excellent separation performance but also overcome additional daunting challenges such as humidity interference and durability requirements for sustainable use. Herein, porous organic crystals of a new macrocycle (CaC9) with superhydrophobic self-healing features are prepared employed purification (>99.99% purity) ternary methane/ethane/propane mixtures under 97% relative humidity. The high selectivity water-resistance attributed unique chemical structure CaC9, possessing an intrinsic 4.2 Å pore along environment modified saturated alkyl chains. Besides, CaC9 exhibit capacity realize in situ reconstruction porosity within 15 min. transformation nonporous state can be easily achieved upon treatment n-hexane vapor, thereby presenting novel solution enhance processes materials. This work introduces molecular-level adsorbent separation, providing valuable impetus designing unexpected functions.

The development of nanoporous metal–organic frameworks (MOFs) capable effectively separating and purifying CH4 is significant importance. High surface polarity suitable pore diameter are two key factors that can synergistically enhance separation performance. Herein, we report hydroxyl-functionalized Al-MOFs (CAU-1-OH CAU-1-(OH)2) for the purification natural gas. They both possess different types nanocages as well a densely surface. Significantly, CAU-1-(OH)2 demonstrated exceptional selectivity in C3H8/CH4 (50:50, v/v) C2H6/CH4 v/v), with values 990 36, respectively, surpassing those most reported porous materials. dynamic breakthrough experiment ternary mixture generate pure exceeding 3.46 mmol g–1, which adequately demonstrates actual performance CAU-1-(OH)2. Finally, molecular simulations situ infrared experiments verified high affinity toward C3H8 C2H6, giving rise to loading capacity C2H6.

Separating natural gas to obtain high-quality C1–C3 alkanes is an imperative process for supplying clean energy sources and high valued petrochemical feedstocks. However, developing adsorbents which can efficiently distinguish CH4, C2H6, C3H8 molecules remains challenging. We herein report ultra-stable layered hydrogen-bonded framework (HOF-NBDA), features differential affinities adsorption capacities molecules, respectively. Breakthrough experiments on ternary component mixture show that HOF-NBDA achieve efficient separation of CH4/C2H6/C3H8 (v/v/v, 85/7.5/7.5). More importantly, realize recovery from mixture. After one cycle breakthrough, 70.9 L·kg–1 high-purity (≥ 99.95%) CH4 54.2 (purity ≥99.5%) could be obtained. Furthermore, excellent performance under different flow rates, temperatures, humidities endow ideal adsorbent the future purification.
