The preferential adsorption of ethane over ethylene would significantly simplify the overall ethane‐ethylene separation scheme for ethylene purification. Ethane‐selective adsorbents are still lacking compared to ethylene‐selective adsorbents. We discovered that a fluorinated Metal‐Organic Framework, FMOF‐2, exhibits preferential adsorption of ethane over ethylene at pressures in the range of 40 kPa with ideal adsorbed solution theory selectivity of 3.3. The material was characterized by X‐ray diffraction, argon physisorption at 87 K, thermal gravimetric analysis, scanning electron microscope (SEM) image, and X‐ray photoelectron analysis. Exposed fluorine functional groups on a porous material produced via a hydrogen‐bonding type electrostatic attraction are thought to serve as ethane adsorption sites.

氟化金属有机骨架FMOF-2，用于乙烯优先吸附乙烯

乙烷优先于乙烯的吸附将大大简化用于乙烯纯化的整个乙烷-乙烯分离方案。与乙烯选择性吸附剂相比，仍缺乏乙烷选择性吸附剂。我们发现，在40 kPa的压力范围内，氟化金属有机骨架FMOF-2表现出乙烷比乙烯优先吸附的乙烷，理想的吸附溶液理论选择性为3.3。该材料的特征在于X射线衍射，87 K下的氩气物理吸附，热重分析，扫描电子显微镜（SEM）图像和X射线光电子分析。通过氢键型静电吸引在多孔材料上暴露的氟官能团被认为是乙烷的吸附位点。
