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.

用于高效分离轻烃的新型笼型金属有机框架

开发用于分离轻烃混合气体的有效物理吸附剂是石化工业中具有挑战性的首要步骤。在这项工作中，我们设计并合成了一种新型笼状金属有机框架 SDU-CP-8。SDU-CP-8 具有椭圆形笼状结构，并呈现出独特的三节点（4,6,8）连接网状结构。此外，在 273 K 和 100 kPa 条件下，SDU-CP-8 对 C3H8（148.9 cm3 g-1）和 C2H6（126.3 cm3 g-1）的吸附能力显著高于 CH4（16.6 cm3 g-1）。而在 273 K 和 100 kPa 条件下，C2H2（116.1 cm3 g-1）的气体吸收值高于 CO2（61.8 cm3 g-1）。此外，突破实验证明，SDU-CP-8 能有效分离 C3H8 /C2H6/CH4 和 C2H2/CO2 混合气体。这些结果表明，SDU-CP-8 是一种很有前途的吸附剂，可用于 CH4 和 C2H2 的净化。
