Abstract: | The formation of ions in the volumetric reaction of methane and hydrogen with air is analyzed. In methane–air mixtures, the highest concentrations are observed for NO+, NO3
–, CO3
–, CO4
–, OH–, and NO2
– ions. In hydrogen–air mixtures, maximum concentrations are characteristic for NO+, OH–, H3O+, O–, and O2
– ions. In both rich and lean mixtures after ignition there is a long time interval during which the ion concentrations are far from equilibrium. The duration of this interval and the ion concentrations in it depend on the initial parameters of the mixture and the air–fuel ratio. Key words: volumetric reaction of methane with air, ion-molecular reactions, kinetics, ions. |
