Atmospheric Sulfr hexafluoride: Trends, Sources, and Prospects

Sulfur hexafluoride (insulating gas) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, gaz sf6 will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought gaz sf6 into the climatic impact discussion aimed at reductionGet price

Insights on decomposition process of c-C4F8 and c-C4F8/N2

It was found that the decomposition of c-C 4 F 8 /N 2 mainly produces CF 2, F, CF 3, CF, C, CF 4 and C 2 F 4. c-C 4 F 8 can decompose to C 2 F 4 by absorbing 43.28 kcal/mol, which is the main decomposition path and this process easily occurs under high temperature. There is a dynamic equilibrium process among the various produced radicalsGet price
