Molecular insights into the role of O2 in reversed C2H6/C2H4 separation on metal-organic frameworks

Ruihan Wang et al.

Summary: This study investigated the influence of oxygen (O2) on the C2H6/C2H4 selectivity of a Cr-BTC MOF using density functional theory calculations and grand canonical Monte Carlo simulations. The results showed that O2 formed a superoxo site by antiferromagnetic coupling to the open Cr site, decreasing the dipole moment of the open metal site. The presence of the superoxo site blocked the interaction between Cr and C2H4, altering the gas selectivity.

Combination of Low-Polar and Polar Binding Sites in Aliphatic MOFs for the Efficient C2H6/C2H4 Separation

Jingyi Zhou et al.

Summary: We reported two isostructural pillared-layer metal-organic frameworks, ZUL-C3 and ZUL-C4, which were constructed by mixed polycycloalkane-type ligands. Their low-polar pore environment and more accessible low-polar C-H binding sites on the pore surface facilitate more van der Waals interactions with C2H6, while the carboxylic groups distributed at four corners of the pores form stronger and more dipolar interactions with C2H6, resulting in a good C2H6/C2H4 uptake ratio and high C2H4 productivity.

Summary: The development of ethane-selective adsorbents for purifying ethylene into polymer-grade materials is challenging but meaningful. By tailoring the pore chemistry of a metal-organic framework, high performance adsorbents like BUT-10 can be constructed to enhance C2H6 adsorption ability. Computational studies have shown that multiple adsorbate-framework interactions in the appropriate pore environment lead to stronger adsorption affinity for C2H6. Breakthrough experiments using BUT-10 as a C2H6-selective adsorbent have successfully produced polymer grade C2H4 directly from mixtures under ambient conditions.
