Abstract
A comprehensive experimental and kinetic study on the low temperature oxidation and pyrolysis of iso-octane and CNPC 92# was conducted. Species profiles measurements were performed in a jet-stirred reactor (JSR) at the temperature range of 500–1300 K under atmospheric pressure, with a fixed residence time of 2.0 s and for the equivalence ratios ranging from 0.5 to ∞ (pyrolysis). Three kinetic models were adopted to simulate mole fraction profiles of major species in the oxidation and pyrolysis of iso-octane, and sensitivity analysis was also conducted using the model which preformed best. In addition, a detailed gasoline surrogate kinetic model was developed including five representative fuels in gasoline. This kinetic model and a TRF model containing three individual fuels from KAUST were verified by low temperature oxidation and pyrolysis experiment data of CNPC 92#. The results show that prediction profiles by the five-component model and measured mole fraction of major intermediates are in a better agreement than TRF model.
