Chemical kinetic modeling of the oxidation of large alkane fuels: N-octane and iso-octane

Experimental Study of 1 Atmosphere, Rich, Premixedn-heptane and iso-octane Flames

“…The main consumption path for alkyl radicals forms a smaller alkyl radical and an olefinic compound by thermal decomposition which occur preferentially in ! 'i-position with respect to the radical carbon site (Dryer and Glassman, 1979;Warnatz, 1984;Axelsson et at.• 1986;Westbrook and Pitz, 1987). When applied to the n-heptane molecule this rule leads to the following reactions:…”

Experimental Study of the Chemical Structure of Low-Pressure Premixed n>Heptane-02-Ar and lso-Octane-02-Ar Flames

“…The former produce alkyl radicals (respectively n-heptyl and iso-octyl radicals) that fall. apart by thermal decomposition reactions to form a smaller alkyl radical and an olefinic compound (Dryer and , 1979;Warnatz, 1984;Axelsson et al, 1986). Decomposition of the alkyl radical occurs preferentially in {3-position with respect to the radical carbon site.…”

“…In the next step (Reaction G) C 5 M" isomerizes to C; (Figure 3b), a species which contains both a radical site and a double bond. Reaction G is called a /3 scission reaction [47] because the C-C bond two carbons away (or "/3") from the radical site is broken during this isomerization reaction. (Two other C-C bonds can also break via a /3 8 scission reaction; products of those reactions are not considered here.)…”
