The removal of carbon dioxide (CO2) from acetylene (C2H2) represents a pivotal industrial process for the production high-purity C2H2. Nevertheless, separation C2H2 and CO2 is challenging due to their highly similar molecular sizes physical properties. In this work, we report fine regulation sql layered coordination polymer (termed NTU-107) into rare fsc open framework NTU-108) with naphthalenedisulphonic acid pillar selective capture CO2-contained mixtures. NTU-107 was prepared by reaction 4-(1H-imidazol-1-yl)benzoic (L1) ligand Cu2+ ion, showing pore size 4.2 Å. After inserting 1,5-naphthalenedisulphonic between layers, new pillar-layered (5.8 Å) sulphonic functional sites prepared. Single-component gas adsorption experiments breakthrough demonstrated that NTU-108 accessible exhibits high absorption capacity dynamic C2H2/CO2 performance at room temperature.

C2 hydrocarbon separation from methane represents a technological challenge for natural gas upgrading. Herein, we report new metal–organic framework, [Cu2L(DEF)2]·2DEF (UNT-14; H4L = 4,4′,4″,4‴-((1E,1′E,1″E,1‴E)-benzene-1,2,4,5-tetrayltetrakis(ethene-2,1-diyl))tetrabenzoic acid; DEF N,N-diethylformamide; UNT University of North Texas). The linker design will potentially increase the surface area and adsorption energy owing to π(hydrocarbon)−π(linker)/M interactions, hence increasing hydrocarbon/CH4 separation. Crystallographic data unravel an sql topology UNT-14, whereby [Cu2(COO)4]···[L]4– paddle-wheel units afford two-dimensional porous sheets. Activated UNT-14a exhibits moderate porosity with experimental Brunauer–Emmett–Teller (BET) 480 m2 g–1 (vs 1868 crystallographic data). considerable uptake capacity under ambient conditions vs CH4. GCMC simulations reveal higher isosteric heats (Qst) Henry's coefficients (KH) related literature MOFs. Ideal adsorbed solution theory yields favorable selectivity equimolar C2Hn/CH4 mixtures, attaining 31.1, 11.9, 14.8 mixtures C2H6/CH4, C2H4/CH4, C2H2/CH4, respectively, manifesting efficient highest Qst being ethane are also desirable technologically; it is attributed greatest number "agostic" or other dispersion C–H bond interactions (6) 4/2/4 ethylene/acetylene/methane.

Natural gas upgrading is industrially important for its utilization, wherein the recovery of heavier alkanes, such as ethane (C2H6) and propane (C3H8) certain economic importance. Hydrogen-bonded organic frameworks (HOFs) have shown great potential separating alkanes. Such a type porous material so flexible that it very challenging to show permanent porosity separation. Here, we report an ultramicroporous hydrogen-bonded framework HOF-MTBA effective separation ternary mixtures C3H8/C2H6/CH4 binary C2H6/CH4 C3H8/CH4. Upon solvent exchange, accommodates dichloromethane molecules new phase, which can be readily transformed into open phase after desolvation. Single-component sorption experiments exhibit high low-pressure uptakes C2H6 (0.71 mmol/g, at 10 kPa 298 K) C3H8 (1.2 5 K), are higher than many reported adsorbents (0.16–0.73 mmol/g) under same conditions.
