The detailed pyrolysis kinetic model containing 255 species and 960 reactions for n-decane was developed from a classical kinetic model from hydrocarbon combustion (USC Mech Ⅱ) and many paraffins reation rate constants.Meanwhile,a reduced mechnism containing 61 species and 204 reactions was developed by i using the Path Flux Analysis.The detalied and reduced mechanisms were validated by the synchrotron vacuum ii ultraviolet photoionization mass spectrometry with molecular beam sampling technique.The mole fraction profiles of the main pyrolysis species predicted by the detailed and reduced mechanisms are in good agreement with the experimental measurements.In ad-dition,the computational efficiency of CFD using reduced mechanism is significantly higher than that using detailed mechanism.
