Özet

Studies of elemental and organic carbon formation/oxidation in diffusion or rich premixed combustion systems focus mostly on soot particles and polycyclic aromatic hydrocarbons. In recent years, a new class of carbon compounds, in the form of molecular clusters (nanoparticles) of organic composition has been inferred, detected and modeled within and at the exhausts of a variety of combustion systems. This new category of pollutants seems to be related to the formation processes of ultrafine particles found at the exhaust of practical combustion systems, which are considered dangerous to human health. Heavy molecular weights and extremely small sizes of nanoparticles prevent their detection by ordinary techinques (e.g., GC-MS), particularly in combustion conditions.
