Experimental and numerical study of the oxidation of propylene oxide in an isothermal jet-stirred reactor

Propylene oxide (С$_3$H$_6$O) is an intermediate product of oxidation of heavy hydrocarbons and can be used as an additive to conventional fuels to reduce soot emissions. New experimental data on the oxidation of С$_3$H$_6$O at low temperatures were obtained using an isothermal jet-stirred reactor. Experiments were carried out at temperatures of 600–1300 K and a pressure of 1 atm, and the residence time of the gas mixture in the reaction vessel was 1 s. Five detailed chemical kinetic mechanisms taken from the literature were tested. A mechanism that has the best predictive ability at low temperatures was identified. The mechanisms were also tested against experimental data on the structure of С$_3$H$_6$O flames. It has been found that at the moment there is no model that can correctly describe the combustion and oxidation of С$_3$H$_6$O at both low and high temperatures.
