Morphological and chemical characterization of soot

Abstract The morphology, microstructure and chemical composition of soot particles emitted directly from biofuel cook stoves have been studied by using high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS) and ion beam analysis (IBA) techniques. Freshly emitted soot particles were collected using an eight stage cascade impactor that separates Chemical Composition of Diesel/Biodiesel Particulate Jun 30, 2017 · The addition of biodiesel to diesel changes the particulate composition towards more oxygenated constituents, such as carbonyl groups attributed to methyl ester CH3O+ fragments of unburned biodiesel. Fuel-specific fragments have been identified, such as C3H7O+ for diesel, and C2H3O2+ and CH3O for biodiesel.

  • HighlightsIntroductionMaterials and MethodsResults and DiscussionConclusionsAcknowledgement Microstructure and Chemical Composition of Particles Among globally relevant combustion sources, such as diesel emission and biomass burning, gas flaring remains the most uncertain. In this study, small-scale turbulent gas flaring was used to characterize particulate emissions produced under different operating conditions, such as various burner diameters and exit velocities. The composition of the fuel was also varied by modifying the
