Dagaut, Philippe published the artcileEmission of carbonyl and polyaromatic hydrocarbon pollutants from the combustion of liquid fuels: impact of biofuel blending, Formula: C9H18O2, the main research area is carbonyl polyaromatic hydrocarbon biofuel pollutant combustion.
The combustion of conventional fuels (diesel and Jet A-1) with 10-20% vol oxygenated biofuels (ethanol, 1-butanol, Me octanoate, rapeseed oil Me ester (RME), di-Et carbonate, tri(propylene glycol)methyl ether, i.e., CH3(OC3H6)3OH, and 2,5-dimethylfuran (2,5-DMF)) and a synthetic paraffinic kerosene (SPK) was studied. The experiments were performed using an atm. 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 anal. Polyaromatic hydrocarbons (PAHs) were extracted from the soot samples. After fractioning, they were analyzed by high-pressure liquid chromatog. (HPLC) with UV and fluorescence detectors. C1 to C8 carbonyl compounds (CBCs) 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 CBCs and PAHs adsorbed on soot. The global concentration of 18 PAHs (1-methyl-naphthalene, 2-methyl-naphthalene, and the 16 U.S. priority EPA PAHs) on soot was considerably lowered using oxygenated fuels, except 2,5-DMF. Conversely, the total carbonyl emission increased by oxygenated biofuels blending. Among them, ethanol and 1-butanol were found to increase considerably the emissions of CBCs.
