摘要

The incomplete combustion of hydrocarbons leads to the formation of, among others, Polycyclic Aromatic Hydrocarbons (PAH), which themselves lead to the formation of soot. Those systems are known health hazards and atmospheric pollutants It is generally accepted that the rate-limiting step to the formation of PAH is the formation of a first aromatic ring. The aim of this thesis is to develop a sub-mechanism for the formation of a first aromatic ring and to test it in a combustion model. To achieve this, we need to determine the thermodynamic properties (ΔH°_f, S and C_p) of all the intermediates, and the rate constants for all reactions considered. Most of the systems to be studied are quite unstable, therefore, quantum chemistry is used to obtained the desired properties.
