“…The importance of benzene formation via this route has been experimentally showed by Kopinke et al [73]. Finally, toluene is formed by termination between phenyl radical and CH 3 or by termination between H atom and benzyl radical.…”

“…The model explains the formation of cyclopentadienyl radical and cyclopentadiene from the addition of acetylene on propargyl radical (C 3 H 3 ) [29]. Benzene is formed through three pathways (Figure 8): the combination of two propargyl radicals or of propargyl and allyl radicals (C 3 pathway) [29,30], the combination of cyclopentadienyl and methyl radicals through the formation of methyl-cyclopentadiene (C 5 pathway) [31][32][33][34], and the addition of acetylene to C 4 radicals followed by a ring closure (C4 pathway) [35].…”

“…Kopinke, Ondruschka and Zimmerman (1988) examined the thermal conversion of ,4C labelled [Methyl-v'C] methylcyclopentadiene and its selectivity to products in an atmospheric flow reactor for the 873 K to 1053 K temperature range at a residence time of 1.0 second. Radio gas chromatography was used to examine the position of the 14C label in the pyrolysis products.…”

Experimental and detailed chemical kinetic modeling has been performed to investigate aromatic and polycyclic aromatic hydrocarbon (PAH) formation pathways in a premixed, rich, sooting, propane-oxygen-argon burner stabilized flame. An atmospheric pressure, laminar flat flame operated at an equivalence ratio of2.6 was used to acquire experimental data for model validation. Gas composition analysis was conducted by an on-line gas chromatograph/mass spectrometer (GC/MS) technique. Measurements were made in the main reaction and post-reaction zones for a number of low molecular weight species, aliphatics, aromatics, and polycyclic aromatic hydrocarbons (PAHs) ranging from two to five-fused aromatic rings.Reaction flux and sensitivity analysis were used to help identify the important reaction sequences leading to aromatic and PAH growth and destruction in the propane flame. Benzene formation was shown to be dominated by the propargyl recombination reaction. A secondary benzene formation pathway occurred from the reaction sequence of allyl plus propargylleading to fulvenc and H-atoms whereupon the fulvene is converted to benzene by H-atom catalysis.Large negative sensitivity coefficients were calculated for the H,CCCH + H-CJH, + H, reaction in the propargyl, benzene, and naphthalene sensitivity analysis study. This result implicates propargyl consumption by H-atoms as an important reaction step that limits aromatic and PAH growth.Naphthalene formation through the reaction step of cyclopentadienyl self-combination and phenanthrene formation from indenyl and cyclopentadienyl combination were shown to be plausible global reaction steps for PAH production.
