Detection of Oxygenated Aromatics in Atmospheric Anisole Flames
Résumé
Despite the undeniable interest presented by biofuels, their combustion processes are likely to modify the formation of aromatic species, especially oxygenated aromatics, that may profoundly modify the properties of the formed soot particles. However, the kinetics of oxygenated aromatics are not well studied yet. In this work, a laminar premixed flame of anisole (a surrogate for lignin-based biofuels) and hydrocarbon fuel blend was investigated under fuel-rich conditions. Chemical products sampled from the flames were analyzed using 1D and 2D Gas Chromatography that have enabled us to separate and identify around 100 aromatic species including 60 oxygenated ones with different functional groups (alcohols, ethers, aldehydes, ketones, esters, acids).
