  • Separation of SF6 from SF6/N2 mixture using metal–organic

    Feb 15, 2015 · The adsorption capacity of SF 6 on the MIL-100 (Fe) granule was 1.658 mmol/g, and the selectivity of SF 6 over N 2 was 24.4 at 1 bar and 298 K. Compared to Zeolite 13X, the breakthrough time of the MIL-100 (Fe) granule was much shorter than Zeolite 13X at 1 bar, but the breakthrough time became similar with Zeolite 13X at 9 bar.
