Abstract :
A study has been made of the formation of PAH from biodiesel and conventional diesel fuel using a flow cell reactor at temperatures of 600–900 °C. The reaction mechanism has been validated by modelling studies using Chemkin. Pyrolysis of 9-[13C]methylphenanthrene was undertaken to investigate the demethylation reaction of methyl-PAH compounds present in the original petroleum diesel. The product profiles obtained are shown to be similar for all fuels studied, pointing to a commonality of mechanism after the decomposition of the parent hydrocarbon. Dealkylation was demonstrated as the main reaction using the 9-[13C]methylphenanthrene, however other [13C] labelled species were also formed.
