Abstract
The development of effective physical adsorbents for the separation of light hydrocarbons gas mixture is a challenging and prime step in the petrochemical industry. In this work, we designed and synthesized a novel cage-based metal−organic framework, SDU-CP-8. The SDU-CP-8 featuring an ellipsoid-shaped cage and exhibits distinct connectivity with a 3-nodal (4,6,8)-connected net. In addition, SDU-CP-8 displays remarkable adsorption capacities for C3H8 (148.9 cm3 g−1) and C2H6 (126.3 cm3 g−1) significantly higher than CH4 (16.6 cm3 g−1) at 273 K and 100 kPa. While, the gas uptake value for C2H2 (116.1 cm3 g−1) is higher than CO2 (61.8 cm3 g−1) at 273 K and 100 kPa. Moreover, breakthrough experiments demonstrate that SDU-CP-8 can effectively separate C3H8 /C2H6/CH4 and C2H2/CO2 gas mixtures. These results show that SDU-CP-8 is a promising adsorbent for both CH4 and C2H2 purification.
