journal contribution

component in transportation fuels. Nowadays, experimental
data about n-tetradecane are rare, especially for
the gas-phase kinetic experiment, which limits the development and
updating of the combustion kinetic model of n-tetradecane.
This paper reports the first effort on investigating the gas-phase
pyrolysis of n-tetradecane. The experimental conditions
cover temperatures of 832–1281 K and pressures of 30 and 760
Torr, while photoionization mass spectrometry was applied for speciation.
A comprehensive model of n-tetradecane combustion
was also constructed. The validation data include new pyrolysis data,
literature oxidation data, and global combustion parameters. Modeling
analysis tools were also applied to reveal major reactions for the
pyrolysis and oxidation of n-tetradecane. Primary
dissociation and H-abstraction reactions have the largest contributions
and sensitivity coefficients for n-tetradecane decomposition
under present pyrolysis conditions. HO2 plays a significant
role on ignition delay times, while C0–C3 reactions dominate laminar burning velocities of n-tetradecane.
