Stabilized three-stage oxidation and its pressure dependence of stoichiometric n-heptane/air mixture were examined using a micro flow reactor with a controlled temperature profile. Especially at low velocity condition, three weak flames were observed as spatially separated flames in the different temperature ranges, and these flames correspond to low-temperature reaction and separated high-temperature reactions. As increasing pressure, the first and second flames got stronger whereas the third flame got relatively weakened. Reaction path analysis and sensitivity analysis were conducted to get a better comprehension of such pressure dependence. The results showed that the reaction rate of the third flame depends on that of CO and H_2/O_2 reactions, thus second explosion limit of H_2/O_2 plays a key role in the pressure dependence of the third flame.
