1. Introduction. Reducing greenhouse gases to prevent global warming is a significant concern worldwide. Sulfur hexafluoride (SF 6), whose global warming potential (GWP) is 23,900 times that of carbon dioxide, has a residence time of 3,200 years in the atmosphere (Han et al.

Introduction Sulfur hexafluoride (SF 6) represents the best insulating gas available in the electrical industry, with excellent dielectric and arc-quenching properties. It is also used in several other applications, including thermo-acoustic insulator for windows, and as a contrast agent in medical applications.
Hydrate–based capture and storage of sulfur hexafluoride (SF 6) was studied. Thermodynamic properties of SF 6 hydrate were determined. Vibrational band and growth mechanism of SF 6 hydrate were identified. Lower pressure aids in promoting SF 6 hydrate formation in seawater system. SF 6 hydrate shows an efficient wallcrawling ability.
Introduction As an artificial gas, sulfur hexafluoride (SF 6) was first identified by Henri Moissan and Paul Lebeau in 1900 (Christophorou et al., 1997). It is an odorless, colorless, non-toxic, and non-flammable gas with exceptionally stable structure comprising of six fluorine atoms firmly bonded to a central sulfur atom.
High pressure excess adsorption isotherms of sulfur hexafluoride (SF) on metal–organic frameworks Cu (btc) (HKUST-1, btc – benzene-1,3,5-tricarboxylate), Fe FO (H O) (btc) F (H O) O (dmcpz) adsorption. At high pressure, mesoporous MIL-101 and DUT-9 have the highest storage capacities for both gases among the MOFs investigated.
Thermodynamic results for the three–phase coexistence conditions of the SF 6 hydrate system demonstrated that SF 6 is well–suited for storage using hydrate–based technology. Kinetically, gas consumption in pure water was greater than in seawater, attributed to the effect of salt on the phase equilibrium condition.
Stability The SF 6 substitute gas is expected to be thermal and electrical stable during a long-term operation. Current investigations have explored the decomposition mechanisms and properties of various gases (Zhang et al., 2017c; Li et al., 2018b).
