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. After fractioning, they were 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. The global concentration of 18 PAHs (1-methyl-naphthalene, 2-methyl-naphthalene, and the 16 US priority EPA PAHs) on soot was considerably lowered using oxygenated fuels, except 2,5-dimethylfuran. Conversely, the total carbonyl emission increased by oxygenated biofuels blending. Among them, ethanol and 1-butanol were found to increase considerably the emissions of carbonyl compounds.

AbstractThis work presents the adsorption process of nitrogen compounds, namely quinoline (Q), pyridine (Pyr), and indole (In), from liquid fuels such as gasoline and diesel containing dibenzothiophene (DBT) as sulfur-containing molecules. These compounds were adsorbed on mesoporous materials, namely SBA-15 and SBA-16, in calcined form in batch mode using dodecane as a solvent represent to a diesel mixture. The main conclusion of this research is that SBA-15 showed a higher nitrogen adsorption capacity than SBA-16 for all molecules containing nitrogen and sulfur. A comparative study of nitrogen and sulfur adsorption confirms that selective removal of nitrogen compounds from fuels using SBA-15 was better than that of sulfur compounds. Moreover, an increase in the adsorption of Q was found with SBA-15 material compared to SBA-16. To explain this behavior, the solids were characterized using X-ray diffraction (XRD), nitrogen physisorption, and High-Resolution Transmission Electron Microscopy (HRTEM). A pseudo-second-order kinetic model, rather than a first-order one, fitted the nitrogen adsorption data best. Moreover, the Langmuir model was suitable for describing the adsorption of nitrogen compounds from simulated diesel fuel, instead of the Freundlich model, which means that nitrogen compounds are adsorbed in a monolayer.
