    Nov 23, 2019 · Also, pure CO2 has been discounted as a viable alternative for the purposes of this study, due to the increase in switchgear physical dimensions, relative to a similarly rated SF6 unit. However, CO2 mixtures make up some of the gas mixtures which have been trialled previously by developers.

  • 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.
