Popis: We demonstrate that carbon molecular weight growth chemistry can continue to occur when polycyclic aromatic hydrocarbons (PAH), produced by localized fuel rich pockets within an incinerator, disperse into the near-stoichiometric bulk flow characteristic of the unit. Naphthalene, a model PAH, was added to a near-stoichiometric (φ = 1.2) post-flame combustion flow produced by premixed C2H4/O2/N2/Air combustion in a jet-stirred/plug-flow reactor system (JSR/PFR), and the results compared against those from a fuel rich (φ = 2.2) post-flame combustion flow without naphthalene addition. In both experiments, the PFR was sampled for soot (CH2Cl2 insolubles), tar (CH2Cl2 solubles; PAH), C2H2 and other light gases. The results indicate that naphthalene addition to the φ = 1.2 flow produces PAH in the naphthalene (M W = 128) to cyclopenta[cd]pyrene(MW = 226) fraction at exactly the same total mass concentration as observed in the φ = 2.2 flow without naphthalene addition. Similarly, the rate of growth of so...
