Abstract

This work reports the investigation on premixed flames of tetralin at 30 Torr and equivalence ratios of 0.7 and 1.7. Measurements of the flame chemical structure, i.e. identification and mole fraction measurements of radicals, isomers and polycyclic aromatic hydrocarbons (PAHs), were performed using synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS). A kinetic model with 296 species and 1571 reactions was developed and validated by the flame chemical structure data in this work. Modeling analysis demonstrates the key reaction pathways in tetralin decomposition and aromatics growth. It is concluded that H-atom abstraction reactions dominate the consumption of tetralin under premixed flame conditions, while oxidation reactions play more important roles in the lean flame. Indene and naphthalene are abundantly produced in the tetralin flames since they are key decomposition products of tetralin. Consequently their radicals play important roles in the aromatics growth process and stimulate the production of many typical large PAHs.
