Abstract: This paper presents a numerical and experimental study of the effect of flame-retardant additives on the autoignition of methane behind shock waves. It is shown that at a temperature of 11300–1900 K, the compounds CCl$_4$, CF$_3$H, (СН$_3$О)$_3$РО not only do not suppress ignition but significantly reduce the induction time of methane-oxygen mixtures. A kinetic mechanism is proposed which relates the promoting effect to the reactivity of the pyrolysis products of the additives.

Keywords: methane, ignition, flame inhibition, additives, halogen, phosphoru.
