Polycyclic Aromatic Hydrocarbons (PAHs) and soot formation in combustion
Fine particles, PM2.5, represent a major threat impacting both the environment and human health, also for the recent studies on their toxicity from different sources. Key steps in the formation of particulate matter include the formation of the first aromatic ring species and the subsequent growth to naphthalene and larger polycyclic aromatic species. The aim of this thesis work is to investigate the kinetics of the soot precursors, that is Polycyclic Aromatic Hydrocarbons (PAHs), in order to study their role in the formation of soot. This kinetic study will be developed using OpenSMOKE++ software, in order to explore different conditions, both in reactors and flames, and compare the model predictions to experimental data. In this way, a better understanding of the soot formation routes will be developed and discussed, with the final aim to reduce PM emissions from stationary and mobile sources (furnaces, power plants, engines etc.).
