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

    Feb 15, 2015 · To overcome this obstacle, Kwon et al. performed an SF 6 /N 2 separation (1.3 vol.% SF 6) using the pressure temperature swing adsorption (PTSA) process to desorb SF 6 efficiently. They obtained an SF 6 purity of 19.5% and a recovery of 50.1% at a 2.5 atm adsorption pressure and a 200 °C desorption temperature.

  • The Kinetic-Molecular Theory | Chemistry for Majors

    The Kinetic-Molecular Theory Explains The Behavior of Gases, Part IMolecular Velocities and Kinetic EnergyThe Kinetic-Molecular Theory Explains The Behavior of Gases, Part IIGlossaryRecalling that gas pressure is exerted by rapidly moving gas molecules and depends directly on the number of molecules hitting a unit area of the wall per unit of time, we see that the KMT conceptually explains the behavior of a gas as follows: 1. Amontons’s law.If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure (Figure 1). 2. Charles’s law.If the temperature of a gas is increased, a constant pressure may be maintained only if the volume occupied by the gas increases. This will result in greater average distances traveled by the molecules to reach the container walls, as well as increased wall surface area. These conditions will decrease the both the frequency of molecule-wall collisions and the number of collisions per unit area, the combined...
