Summary: The development of high-performance adsorbents is crucial for the low-energy separation of acetylene. In this study, a Fe-MOF with U-shaped channels was synthesized. The adsorption isotherms and breakthrough experiments showed that Fe-MOF has a high acetylene uptake and can effectively separate C2H2/CO2 and C2H2/C2H4 mixtures at normal temperatures. The simulation results also demonstrated the strong interaction between Fe-MOF with U-shaped channels and acetylene.

Summary: A new C2H2 adsorption trap (UPC-80) constructed by 4-fold interpenetration nets is reported, which shows high adsorption selectivities of 6.34 and 4.78 for C2H2/CO2 and C2H2/C2H4, respectively. Laboratory-scale fixed-bed breakthrough experiments confirm the efficient separation ability of UPC-80 towards the C2H2/CO2 and C2H2/C2H4 gas mixtures, with negligible capacity loss. Theoretical simulations attribute the good separation performance to the anchoring of C2H2 by two Tb2(COO)6 clusters in adjacent interpenetration nets and the strong electrostatic interaction.

Summary: A systematic study is conducted on the engineering of pore dimensions and pore functionality of fcu-type Y-based metal-organic frameworks (Y-MOFs) using different linear dicarboxylate linkers. The research demonstrates how slight changes in pore size and pore surface chemistry can affect the adsorption preference of C2H6, C2H4, and C2H2 by the MOFs, establishing clear relationships between pore size/pore surface polarity and C-2 adsorption selectivities. A specific compound, HIAM-326, shows remarkable preferential adsorption of C2H6 and C2H2 over C2H4, enabling the one-step purification of C2H4 from C2H6/C2H4/C2H2 ternary mixtures to obtain high purity C2H4 (99.9%+).

Summary: This study reports a robust metal-organic framework (MOF) with methyl-decorated nonpolar pores that achieves one-step purification of C2H4 from binary and ternary C2H6/C2H4/C2H2 mixtures. The MOF exhibits high C2H6 and C2H2 uptakes and surpasses all previously reported MOFs in terms of C2H6/C2H4 selectivity for C2H4 purification. The presence of methyl groups in the pores enhances the adsorption capacity for C2H2 and C2H6 compared to C2H4.

Summary: Adsorptive separation using porous materials is a promising approach for separating alkynes/olefins due to its energy efficiency. However, the deep removal of trace amounts of C2H2 and CO2 from C2H4 using commercial adsorbents is still challenging. In this study, a low-cost inorganic metal cation-mediated mordenite (MOR) zeolite with specific K+ cations acting as a goalkeeper for accurately controlling diffusion channels was developed. The approach achieved exceptional results in purifying C2H4 from ternary CO2/C2H2/C2H4 mixtures.
