Summary:
This report covers the last quarter of the last year of the three-year grant period. In the final project year, we concentrated on the pyrolysis and oxidative pyrolysis of large hydrocarbons and mixtures of large and small hydrocarbons in order to develop the VUV-MS technique for compounds more representative of those in coal pyrolysis applications. Special focus was directed at the pyrolysis and oxidative pyrolysis of benzene and benzene acetylene mixtures. The acetylene/benzene mixtures were used to gain a better understanding of the mechanisms of molecular growth in such systems specifically to look at the kinetics of aryl-aryl reactions as opposed to small molecule addition to phenyl radicals. Sarofim and coworkers at MIT have recently demonstrated the importance of these reactions in coal processing environments. In the past, the growth mechanism for the formation of midsized PAH has been postulated to involve primarily successive acetylene additions to phenyl-type radicals, our work confmns this as an important mechanism especially for smaller PAH but also investigates conditions where biaryl formation can play an important role in higher hydrocarbon formation.
