Biography
Frédérique Battin-Leclerc is a CNRS research director at LRGP in Nancy. Her studies concern combustion, particularly the gas-phase combustion of hydrocarbons including biofuels, in order to develop cleaner-burning automotive fuels. She was awarded an ERC Advanced Grant in 2008, received the CNRS Silver Medal in 2010, and was appointed Knight of the "Ordre national du Mérite" in 2012. In 2012, she was appointed as a Program Co-Chair of the 34th International Symposium on Combustion, in 2018, she was elected to the inaugural class of Fellows of the Combustion Institute, and in 2022, she was honored with the Polany Medal of the Royal Society of Chemistry.
Abstract
As an alternative to petrol derived fuels, a new kind of second-generation biofuel derived from enzymatic hydrolysis lignin, considered nowadays as a waste of the refineries of second-generation bioethanol, has been recently considered. The catalytic production of such biofuels was the topic of the European project EHLCATHOL, in which our work in Nancy aimed at the characterization of the combustion of biofuels derived from this process through the study of a large quantity of arenes (toluene, xylene isomers, styrene) and oxygenated aromatics (phenol, anisole, guaiacol, cresol isomers) as surrogate compounds. The formation of pollutants during the oxidation of these fuels was quantified using a jet-stirred reactor. Their laminar burning velocity was also measured using a flat flame burner based on to the heat flux method. Using this new available experimental database, a unified detailed kinetic model, named COLIBRI, was built to model the combustion kinetics of the studied compounds. This model was validated over a wide range of conditions and allowed to analyze the key pathways of the combustion aromatic compounds.
