  • O-23 Formation Mechanism of polycyclic Compounds from Lignin for Fast Pyrolysis

抄録

Analytical Py-GC/MS method have been used to investigation the reaction mechanism leading to polycyclic compounds, such as polycyclic aromatic hydrocarbons and heterocyclic compounds. Six Phenols with different pendant groups were used in this study. From phenol, naphthalene and dibenzofuran were produced, and proposed the formation mechanism via cyclohexadiene-1-one radical. From m-cresol, three dimethyldibenzofuran derivatives were detected. In these mechanisms, cyclohexadiene-1-one radical is also to be an important intermediate for the dimerization reaction. From guaiacol pyrolysis, a major product was phenol, and small amount of benzofuran was formed. From pyrocatechol, three indanone derivatives were produced via carbon oxide elimination with aromatic ring opening followed by formation of pentadienone. After two proton donation, three pentanone biradicals were subjected to intramolecular coupling to form indanones. From syringol pyrolysis, only benzofuran was produced. From ethylphenol, three kind of benzofuran were detected with different pendant groups, such as methyl, ethyl and ethenyl group. From the results, ortho position to phenol is considered to be an important reaction site for the formation of polycyclic compounds in the pyrolysis.
