摘要: Recently, polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) have been attracting considerable attention owing to their high toxicity. Understanding formation mechanism during combustion processes is important control emission. However, there are few studies that quantitatively investigated OPAH in the fuel-rich oxidation of hydrocarbons, despite availability several on PAH formation. In this study, benzofuran dibenzofuran as OPAHs were quantified toluene using a flow reactor at atmospheric pressure temperature range 1050-1350 K equivalence ratios from 3.0 12.0 residence times 0.2 1.5 s. addition dibenzofuran, 4 types monocyclic 19 also evaluated. The experimental data obtained study compared with those ethylene performed our previous study. existing kinetic model for growth was modified based theoretical predict behavior furan structures. showed significant improvements prediction Based rate production sensitivity analysis model, dominant reaction pathways investigated.
