Abstract
The autoignition delays of stoichiometric methane–ethylene–air mixtures in the initial temperature range T0 = 760–1000 K and at a pressure P0 = 1 and 3 atm were determined experimentally by the method of autoignition in a static reactor and by kinetic modeling. It was found that increasing the pressure reduces the autoignition delay without changing the general nature of its dependence on the concentration of ethylene in the mixture. The effective activation energy of the autoignition delay of methane–ethylene–air mixtures within the measurement error weakly depends on pressure which is confirmed by kinetic calculations. The calculated values of the effective activation energy are in a good agreement with the experimental results.
