演讲摘要:

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.

演讲人简介：

Frédérique Battin-Leclerc is a CNRS research director (Ph.D. at the National Polytechnic Institute of Lorraine in Nancy in 1991) 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 for the project Clean-ICE – Detailed Chemical Kinetic Models for Cleaner Internal Combustion Engines. The project aimed to develop comprehensive chemical kinetic models that describe the formation of minor pollutants—such as aldehydes, aromatic hydrocarbons, and soot precursors—in internal combustion engines. By integrating detailed reaction mechanisms into combustion simulations, Clean-ICE sought to enhance predictive accuracy and support the development of cleaner and more efficient engine technologies

Frédérique Battin-Leclerc won the CNRS Silver Medal in 2010, and was named as a knight in the “Ordre national du Mérite” in 2012. She was elected to the inaugural 2018 class of Fellows of the Combustion Institute, "for innovative research on the formulation of detailed chemical mechanisms for complex practical fuels" and Member of the Board of directors of the Combustion Institute from 2018 to 2022. She was the 2022 recipient of the Polanyi Medal of the Royal Society of Chemistry.
