Abstract

Developing an effective adsorbent for olefin/paraffin separation is a crucial and challenging issue. We have developed an olefin-selective adsorbent by loading two different Cu(II) salts (CuCl2 and Cu(CH3COO)2) within an iron-based metal–organic framework (MOF) and reduced them to Cu(I) species without a high-temperature calcination and an external reducing agent. The successful development of Cu(I)-loaded MOFs was confirmed by characterizations including scanning electron microscope/energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, powder X-ray diffraction, and Brunauer–Emmett–Teller analyses. From the comparisons between Cu(I)-loaded MOFs degassed at two different temperatures, we confirmed that the unsaturated Fe(II) sites within the iron-based MOF can enhance the stability of formed Cu(I) species and thus improve the C3H6/C3H8 selectivity. The resulted Cu(I)-loaded MOF shows large C3H6 uptake (5.15 mmol/g) and high C3H6/C3H8 selectivity (8.9) at 100 kPa and 293 K.
