Abstract
Burner low-temperature flames were established on a powling burner with a diethyl-ether/toluene/air (ethylene content in mixture: 5000 ppm and 10000 ppm) at an equivalence ratio of 2.0, under the atmospheric pressure, in order to better understand the low-temperature oxidation mechanism. Aromatic hydrocarbons and unsaturated aliphatic hydrocarbons measurement are preformed by a liquid- and gas-chromatograph. The temperature in the low-temperature flames were measured using a fine thermocouple. Ethylene addition retarded the low-flame appearance. The generation of the aromatic hydrocarbons is promoted by adding the ethylene only in the yellow column.
