In 1986 he got a Ph.D. in Physical Chemistry from the University Pierre & Marie Curie, Paris, France.He is currently Research Director, Director of ICARE at CNRS Orléans, France, and Director of the Excellence Centre CAPRYSSES. He is Vice-President (President-Elect) of the Combustion Institute and Fellow of the Combustion Institute. He is former Editor of Combustion and Flame and the Proceedings of the Combustion Institute. In 2016 he received the Alfred Egerton Gold Medal, the Combustion Institute “for distinguished, continuing and encouraging contributions to the field of combustion” and the CNRS Silver Medal “for the originality, quality and importance of his work, recognized nationally and internationally".

Abstract：

The combustion of conventional fuels (Diesel and Jet A-1) with 10-20% vol. oxygenated biofuels (ethanol, 1-butanol, methyl octanoate, rapeseed oil methyl ester, diethyl carbonate, tri(propylene glycol)methyl ether, i.e., CH3(OC3H6)3OH, and 2,5-dimethylfuran) and a synthetic paraffinic kerosene was studied. The experiments were performed using an atmospheric pressure laboratory premixed flame and a four-cylinder four-stroke Diesel engine operating at 1500 rpm. Soot samples from kerosene blends were collected above a premixed flame for analysis. Polyaromatic hydrocarbons (PAHs) were extracted from the soot samples and analyzed by high-pressure liquid chromatography (HPLC) with UV and fluorescence detectors. C1 to C8 carbonyl compounds were collected at the Diesel engine exhaust on 2,4-dinitrophenylhydrazine coated cartridges (DNPH) and analyzed by HPLC with UV detection. The data indicated that blending conventional fuels with biofuels has a significant impact on the emission of both carbonyl compounds and PAHs adsorbed on soot. Global toxicity of soot samples was calculated based on the work of Nisbet and Lagoy [Regulatory Toxicology and Pharmacology 16(3), 290-300, 1992] that consider the individual toxicity of PAHs.
