【 摘 要 】

Among the main pollutants emitted into the atmosphere by diesel combustion are the particles. Most of the studies suggest that the greatest impact on health by the particles is caused by some of the organic compounds such as the polycyclic aromatic hydrocarbons, which are highly toxic and carcinogenic compounds. Some of the strategies that are being implemented to mitigate these harmful particles emissions are the use of alternative fuels, such as biodiesel. In this research, the characterization of six fuels (diesel and five biodiesel, obtained from different raw materials) was carried out. Diesel:Biodiesel blends were prepared at 5, 10 and 20% of biodiesel on proportion to the diesel (B5, B10 and B20). Additionally, B100 was analyzed for some biodiesels. The particles emitted by the combustion of the different fuels were sampled and their concentration was determined. The organic compounds were extracted from the particles by ultrasound-assisted extraction and subsequently the polycyclic aromatic hydrocarbons (PAHs) were determined by gas chromatography coupled to mass spectrometry (GC-MS). In this study, it was observed that the use of biodiesel decreases the emission of particle concentration, but it is not significant. In the case of the concentrations of carcinogenic compounds (PAHs), the B20 biodiesel blends emissions had a statistically significant reduction compared to diesel emissions.
