The analysis of the existing mechanisms of polycyclic aromatic hydrocarbons formation in hydrocarbon flames was performed. It was shown that the growth of aromatic molecules includes both the addition of acetylene molecules with subsequent rearrangement of new aromatic structure and coagulation, in which higher aromatic molecules are assembled from different aromatic fragments. The recommended optimal mechanism of aromatic compounds formation includes the irreversible zipper variety of the coagulation mechanism that begins to work, when the number of C-atoms in the formed aromatic particle exceeds 20.
