Shock tube and modeling study of propene pyrolysis

Abstract
The thermal decomposition of propene behind reflected shock waves with 1200 < T5 < 1800 K and 1.6 × 10−5 < ρ5 < 2.7 × 10−5 mol/cm3 was studied by IR laser kinetic absorption spectroscopy and gas‐chromatographic analysis of reaction products. The present data together with earlier shock tube data were satisfactorily modeled with a 51‐reaction mechanism. As the initial step of the reaction, three channels, C3H6 = CH3 + C2H3 (1), C3H6 = H + AC3H5 (2), and C3H6 = CH4 + C2H2 (3), were necessary to interpret all the experimental data. © John Wiley & Sons, Inc.
