Abstract

In this study, the MIL-100(Fe) granule (1.18-1.70mm in size) was successfully synthesized using silica sol as a binder to verify the applicability of MIL-100(Fe) as an adsorbent for SF₆/N₂ separation. There were no significant changes in the physical and the chemical properties after the granulation process of a powder-type MIL-100(Fe) confirmed by XRD, specific surface area and equilibrium adsorption. The adsorption capacity of SF₆ on the MIL-100(Fe) granule was 1.658mmol/g, and the selectivity of SF₆ over N₂ was 24.4 at 1bar and 298K. Compared to Zeolite 13X, the breakthrough time of the MIL-100(Fe) granule was much shorter than Zeolite 13X at 1bar, but the breakthrough time became similar with Zeolite 13X at 9bar. The selectivity of MIL-100(Fe) was also modest for SF₆ over N₂, and showed only a weak pressure dependent in comparison with Zeolite 13X. The regeneration experiments with multiple runs of adsorption/desorption cycles showed that the MIL-100(Fe) granule could be regenerated with much less purge gas than Zeolite 13X, which reveals that the MIL-100(Fe) granule is a promising material for SF₆/N₂ separation.
