Abstract

Efficient one-step separation of ethylene (C₂H₄) and ethane (C₂H₆) is an indispensable and challenging task in petrochemical industry. Herein, we employ a V-shaped pyrazole ligand and zinc ions in tetrahedral configuration to synthesize a layered framework (termed as Zn-BPDP) with rhombic nonpolar channels, which can realize one-step purification of C₂H₄ from C₂H₆/C₂H₄ mixture. The high C₂H₆/C₂H₄ selectivity of Zn-BPDP has been supported by collaborative studies of single-component adsorption isotherms, adsorption heat calculation, ideal adsorption solution theory and theoretical calculation. The breakthrough experiments demonstrate that the mixture of C₂H₆/C₂H₄ (1/99, 1/15, 10/90 and 50/50) can be efficiently separated by Zn-BPDP. More importantly, Zn-BPDP displays outstanding stability in air, high thermal, organic solvents and water, which endows it excellent cycle performance even under high humidity conditions.

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
