2022年3月14日 · Perfluorocyclobutane (c-C 4 F 8, PFC-318, octafluorocyclobutane, CAS 115-25-3) is a potent greenhouse gas (GHG) with a global warming potential of 10 200 on a 100-year timescale (GWP 100) based on a lifetime estimate of 3200 years (Forster et al., 2021).

The following table includes the 100-year time horizon global warming potentials (GWP) relative to CO2. This table is adapted from the IPCC Fifth Assessment Report, 2014 (AR5)i.

Abstract. We reconstruct atmospheric abundances of the potent greenhouse gas c-C4F8 (perfluorocyclobutane, perfluorocarbon PFC-318) from measurements of in situ, archived, firn, and aircraft air samples with precisions of ∼1 %–2 % reported on the SIO-14 gravimetric calibration scale.

a global warming potential of 10200 on a 100-year timescale (GWP100) based on a lifetime estimate of 3200 years (Forster et al., 2021). Mühle et al. (2019) reported that global atmo-spheric emissions of c-C4F8 began in the late 1960s, reaching a plateau of ˘1:2Ggyr1 during the late 1970s to the late

2021年11月4日 · We find a global emission factor of ~0.003 kg c-C4F8 per kg of HCFC-22 FS pyrolyzed. Mitigation of these c-C4F8 emissions, e.g., through process optimization, abatement, or different...

The GWP of c-C 4 F 8 O is about one-third that of SF 6 and its dielectric strength is about 1.2–1.4 times that of SF 6. CO 2 and N 2 are mixed with c-C 4 F 8 O to lower liquefaction temperature and GWP.

2021年6月5日 · Octafluorocyclobutane (C4F8) with a GWP100 (global warming potential) of 10,000 times of CO2 is listed as potent greenhouse gas. Therefore, development of effective control technologies for reducing C4F8 emissions has become an emerging issue to …

More likely seems that the GWP weighted mix of fugitive emissions from 26 category 2E1 from these countries is similar to the mix for category 2E1 from European countries which report 27 individual emissions for category 2E1. For the European Union, c-C4F8 represents ~0–8 % of the GWP weighted 28 PFC mix (CF4, C2F6, C3F8, c-C4F8) from 2E1. If ...
