 abstract={The kinetics of non-catalytic gas-phase pyrolysis and oxidative conversion of light hydrocarbons in the temperature range of 1400-1800 K. has been analyzed. Their fundamental difference from the kinetics of the corresponding catalytic processes has been established. Unlike catalytic processes, at these temperatures the oxidative conversion of C2+ hydrocarbons does not begin with the oxidative stages, but with their pyrolysis, which proceeds much faster than oxidation; and in the specified temperature range C2+ hydrocarbons transform faster than oxygen. The thermal stage of conversion of C2+ alkanes leads to the formation of ethylene, and then the oxidation process proceeds almost identically for all these hydrocarbons. Therefore, the additives of all C2+ alkanes have the same effect on the oxidation and ignition of methane and, consequently, their impurities have the same effect on the knock characteristics of methane. Unlike its homologues, the oxidation of methane proceeds much more slowly and directly when interacting with oxygen, so the conversion of methane and oxygen proceeds similarly. When there is a lack of oxygen, after oxygen conversion is completed, thermal methane pyrolysis occurs at the reached temperature, mainly into acetylene. The subsequent conversion of latter into hydrogen and CO occurs as a result of its interaction with H2O and CO2 formed in the mixture.},
