A Study on Soot Suppression Effects of Oxygenated Fuel Using a Detailed Chemical Kinetic Modeling -2nd Report: Influence of Fuel Mixture Composition on Bell-shaped Temperature Dependence of PAH Yield-

摘要

The influence of fuel mixture composition, especially with oxygenated hydrocarbons, on PAH yields was examined using a detailed chemical kinetic model. N-heptane was selected as a reference fuel. Metha- nol, dimethyl ether (DME), dimethoxy methane (DMM), and methyl butanoate (MB) were used as oxygen- ated hydrocarbons. It has been confirmed that PAH yields reach to the maximum in equilibrium tempera- ture regime between 1600 and 1700K, regardless of fuel mixture composition and initial temperature.
