  • Separation of CF4/N2, C2F6/N2, and SF6/N2 Mixtures in

    The capture and separation of CF4, C2F6, and SF6 and their mixtures containing nitrogen is a challenging process. To solve this, we propose the use of saccharose coke-based carbons as membranes for the adsorption and separation of these gases. By means of advanced techniques of Monte Carlo and molecular dynamics simulations, we have studied the adsorption and diffusion of CF4, C2F6, and SF6 as

  • Dielectric Properties of CF3SO2F/N2 and CF3SO2F/CO2 Mixtures

    CF3SO2F (trifluoromethanesulfonyl fluoride) is a novel substitute to SF6. The AC breakdown tests of pure CF3SO2F, CF3SO2F/N2, and CF3SO2F/CO2 mixtures in a slightly non-uniform electric field were done. The effects of pressure, electrode distance, and mixing ratio on the breakdown characteristics of the CF3SO2F mixtures were obtained and compared with SF6. In order to investigate the
