Los clorofluorocarbonos (CFC) son derivados de los hidrocarburos saturados obtenidos mediante la sustitución de átomos de hidrógeno por átomos de flúor y/o cloro principalmente. Los CFC, son una familia de gases que se emplean en diversas aplicaciones, principalmente en la industria de la refrigeración , y de propelente de aerosoles. 31 Jan 2018 - Trends in atmospheric concentrations of CO2, CH4 and N2O 01 Jun 2016 - Atmospheric concentration of carbon dioxide, methane and nitrous oxide Lignite addition to cattle pens has been reported to reduce NH3 emissions from manure by approximately 60%.

Carbon dioxide (CO2) is the most important anthropogenic greenhouse gas in the atmosphere; however, two other gases, i.e., methane (CH4) and nitrous oxide   As shown in Fig. 1.1, the contribution of CFCs to global warming in the last decade is second only to carbon dioxide (CO2). CFCs are much more potent on a  17 Jun 2020 automobile CO2 emission estimates, traffic CH4 emissions in 2014 to CO2, CH4,N2O, CFC and HFC emissions SAE Technical Paper 01  Systematisk observation av: N2O, CH4, CO2 vissa CFC, CCl4, CH3Cl, CH3CCl3, CF3Br.

CO2 is the most important green-house gas, followed by N2O and CH4 in relative importance. 2011-03-01 · Photocatalysis looks like a panacea to fight all potent greenhouse gases, as photocatalyzed reactions are able to transform or destroy almost all well-mixed, long-lived greenhouse gases – CO 2, CH 4, N 2 O, CFC-12 and CFC-11 – which account for about 96% of the direct radiative forcing, and also short-lived climate forcers like VOCs, NOx, BC and soot that have an important contribution to climate change. LLGHGs (CO 2, CH 4, N2O, CFC-12 and CFC-11) account for about 96% of the direct radiative forcing since 1750. In table 1 the main characteristics of LLGHGs are listed in terms of Global Radiative Forcing in W.m-2, Global Warming Potential GWP 100 (time horizon of 100 years), Atmospheric lifetimes in years and relative importance in %.

Contribution of Passenger Cars and Trucks to CO2, CH4, N2O, CFC and HFC Emissions 2001-01-3758 Global and regional greenhouse gas emissions of natural and anthropogenic origin are estimated. Biogenic CO 2 emissions are globally 770 billion t/year and anthropo-genic CO 2 emissions in 2000 are 28 billion t/year.

In table 1 the main characteristics of LLGHGs are listed in terms of Global Radiative Forcing in W.m-2, Global Warming Potential GWP 100 (time horizon of 100 years), Atmospheric lifetimes in years and relative importance in %. Aside from water vapour, the four principal greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and the halocarbons or CFCs (gases containing fluorine, chlorine and CO2, N2O and CH4 are expressed in ppmv (parts per million by volume – i.e., 397 ppmv of CO2 means that CO2 constitutes 397 millionths of the total volume of the atmosphere) CFC.11 and CFC.12 are expressed in ppbv (parts per billion by volume).
