| 초록 |
Polycyclic aromatic hydrocarbon (PAH) and ion formation in the preflame induction process were investigated using a laminar, diethyl-ether/air, low-temperature, flat stablized burner, operated with an equivalence ratio of 3.0 under an atmospheric pressure. Single-ring aromatics and PAHs ranging from two- to four-fused aromatic rings and unsaturated aliphatic hydrocarbons were measured by liquid- and gas-chromatography. The ion current through an ionization gap has also been measured. Most PAHs and single-ring aromatics were found after the cool flame has degenerated, whereas phenol, acetylene and ion current could be detected at the time when a cool flame appeared. In the blue flame, these species increased markedly as compared to the cool flame period. |
