  • 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
