ethane is the most important representative of organic
substances in theatmosphere. Its concentration significantly
exceeds the concentration of the remaining organic compounds.
In the last decade, the amount of methane in the atmosphere has
increased at a rate of 1% per year. The main sources of methane
emissions are energy, automobile and aviation transport, ferrous
and non-ferrous metallurgy, chemical, petrochemical and coal
industries. Methane ranks second after carbon dioxide in the
efficiency of absorbing thermal radiation of the earth. The
contribution of methane to the creation of the greenhouse effect
is approximately 30% of the value adopted for carbon dioxide.
As the content of methane increases, chemical processes in
the atmosphere change, which can lead to a deterioration of the
ecological situation on earth. The question naturally arises of the
management of the chemical and physical processes in which
methane takes part. The experiment was carried out under the
following conditions: the range of variation of the composition
of the mixture [CH
4
-air]=0-100%, the reaction time of the reaction
is up to 6 hours and at the wavelength of vacuum ultraviolet
radiation (VUV -radiation)- λ=123 nm. In the experiment, the initial
partial pressure of methane was: P1=0.13 kPa and P2=22.5 kPa.
In this case, the partial pressure of air containing 2% of water
vapor varied from 0.13 kPa to 99.8 kPa. The working pressure
range is chosen in connection with the fact that it is at 0.13 kPa to
99.8 kPa that methane absorption is almost completely observed.
