Compact SF6 N2 Mixtures kit

Compact SF6 N2 Mixtures kit

In this paper, SF 6 /N 2 mixture gas with the SF 6 volume ratio from 20% to 40% were used in experiment, and the results were compared with those from pure SF 6 and N 2. The sample mass of cured epoxy resin was 20 mg. The gas flow rate was set as 20 mL/min, the heating rate as 10 °C/min heating in the temperature range from 250 °C to 650 °C. 3.

  • 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
