Experimental and detailed kinetic modeling study of 1-pentanol oxidation in a JSR and combustion in a bomb

Experimental and kinetic modeling study of 1-hexanol combustion in an opposed-flow diffusion flame

“…The dominant initiation step of 1-hexanol decomposition via H-atom abstraction is consistent with literature for other straight chain alcohols, like n-butanol and 1-pentanol [16,23]. In addition, the study by Togbé et al [12] showed that 1-hexanol oxidation in a JSR at 10 atm reacts mostly by H-atom abstraction at low, intermediate, and high temperatures as well.…”

“…The reaction chemistry of C1 to C5 alcohols was extended to include the chemistry of 1-hexanol oxidation. The oxidation scheme for 1-hexanol is similar to that of C4 and C5 alcohols [15,23].…”

“…However, Togbé et al studied the combustion of 1-hexanol in a jet stirred reactor (JSR) and a combustion bomb, and proposed a chemical kinetic mechanism [12]. The chemical kinetic mechanism was based on previously proposed mechanisms for the oxidation of methanol, ethanol, 1-butanol, and 1-pentanol at 1 -10 atm in JSR and flames [15,16,23,34,35].…”

“…More recently, the combustion and kinetics of oxidation of a larger alcohol, 1-pentanol, were also studied [22,23] as bio-pentanol production was shown to be possible through the use of some microbial strains [24]. 1-Hexanol, which is the next subsequent alcohol in size, can be blended with conventional fuels or used as a co-solvent for ethanol-diesel fuel mixtures [25].…”

Combustion Characteristics of C5 Alcohols and a Skeletal Mechanism for Homogeneous Charge Compression Ignition Combustion Simulation

“…19 In general, the octane ratings of C 5 and larger alcohols are lower than those of C 1 -C 3 alcohols; this higher propensity for ignition (increased cetane number) makes larger alcohols suitable for compression-ignition (CI) engine applications. 1 20 Attention to alcohol combustion research on a C 5 family of alcohols, including npentanol [21][22][23][24][25] , iso-pentanol (3-methyl-1-butanol, ) [26][27][28][29][30] , and 2-methylbutanol (2-methyl-1-butanol, ) [31][32][33][34] has increased in recent years because longer-chain alcohols are better suited for combustion engines. However, there have been limited studies on C 5 alcohol combustion.…”
