Pressure and Temperature Dependent Formation Process of up to Triple-Ring PAH from Benzene 2008-01-2437

The formation pathway for poly aromatic hydrocarbons (PAHs) has been studied by not only fundamental chemists but also motor engineers due to the formation of nanoparticle precursors and soot in vehicle emissions. In this study, the formation process of up to triple-ring PAHs was investigated using a flow tube reactor. The gaseous products from the pyrolysis of benzene were analyzed by using GC-MS in the temperature range of 850 - 1277 K and pressure range of 50 - 760 mmHg. We found that PAH products formed at temperatures greater than 1050 K, and the formation process was pressure dependent.
