Probing pyrolytic PAH chemistry in high-repetition-rate shock tube coupled to synchrotron-based double imaging photoelectron/photoion coincidence spectroscopy

Résumé

The aim of the present work is to present the results of the first pyrolytic study on aromatic chemistry performed with the HRRST/i2PEPICO techniques, and to illustrate the capabilities of such techniques in relation to the PAH formation chemistry. For this purpose, toluene was chosen as a fuel due to its relevance as a fuel surrogate component and as intermediate for the PAH appearance and growth. This study complements the literature works on the kinetics of toluene pyrolysis, which includes, among the others, speciation studies using conventional high-pressure shock tube techniques and atmospheric and sub-atmospheric flow reactors. In particular, the HRRST/i2PEPICO coupling may be used to overcome some of the limitations in the conventional shock tube / gas chromatography techniques, such as condensation of heavy compounds and lack of isomer specificity.
