Abstract
Propylene oxide (C3H6O) 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 C3H6O 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 C3H6O flames. It has been found that at the moment there is no model that can correctly describe the combustion and oxidation of C3H6O at both low and high temperatures.
