Abstract—An extended kinetic model was used to carry out the comparative analysis of the kinetics of C₃H₈
and n-C₄H₁₀ oxidation and the kinetics of the oxidation of their thermal destruction products in the mixtures with
air. It was shown that the induction period and the duration of combustion for the destruction products are sub-
stantially shorter than those for individual hydrocarbons. The dynamics of the formation of nitrogen oxides and
other environmental hazards is considered. It is shown that the time required to attain the equilibrium concen-
trations of nitrogen- and carbon-containing components may substantially (hundred-fold) differ from the time
required to attain the maximum values of T and virtually equilibrium concentrations of H₂O, CO₂, and N₂.
