Ionic Liquid-Functionalization Metal-Organic Framework for Efficient C2h2/Co2 Separation

Опубликована: Янв. 1, 2025

Efficiently sieving C2H2 from CO2 remains a daunting challenge due to their similar molecular sizes and physical properties. To address this issue, we have developed novel strategy by functionalizing metal-organic frameworks with ionic liquid, making them effective adsorbents for CO2. The constructed model material of MIL-101-Cr-EMC (EMC = 1-ethyl-3-methylimidazolium chloride), exhibits both high capacity (94.2 cm3/g at 298 K 1.0 bar) outstanding selectivity over (8.5). Notably, 50 kPa, shows C2H2/CO2 5.4, which is 105 times higher than that the control group (MIL-101-Cr, 0.000054) under same conditions. This highlights critical role liquid functionalization in enhancing separation performance frameworks. work not only positions as promising candidate efficient separation, but also introduces developing advanced incorporation liquids into porous materials.

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. The adsorptive selectivities C3H8/CH4 calculated 52.7 14.0. breakthrough experiment demonstrates high-purity CH4 obtained from C3H8/C2H6/CH4, C3H8/CH4, C2H6/CH4, respectively.
