摘要：

According to shock tube model, the formation of benzene, naphthalene, phenanthrene and pyrene was analyzed by simulating their production rate through ROP to investigate the PAHs formation paths of oxygenated fuels. The results show that the magnitude of production rate of ethanol, DME and DMC is orderly decreased with initial equivalent ratio of 1.0 and temperature of 1600 K. The polymerization of propargyl is the main path for benzene formation. Naphthalene is formed mainly through second HACA reaction and combination reaction of phenyl and vinyl acetylene. Phenanthrene and pyrene are mainly formed through HACA reaction. H and OH radicals play an important role in the oxidation of PAHs. In the reaction of third body M, ethanol can inhibit PAHs formation. DME has slight effect on PAHs formation, while DMC can promote PAHs formation.
