OPAHs and SPAHs are highly genotoxic and would largely be formed during the thermal conversion of lignin. Herein, the distribution of OPAHs and SPAHs in lignin pyrolytic tar at different temperatures is elaborated with ESI (-) FT-ICR MS and GC-MS, and the formation routes of two typical OPAH and SPAH are deeply explored via DFT. It is found that most of oxygen-containing compounds convert to phenols and their homologues such as guaiacol (a typical precursor of OPAHs) with the temperature increased. The tar prepared at high temperature contains disulfide, thiophene and thiophene homologues, which are typical precursors of SPAHs. FT-ICR-MS strongly suggests that molecular mass of OPAHs and SPAHs compounds mainly concentrates between 200 Da and 400 Da with carbon atom number from 5 to 25 and DBE from 4 to 15. Higher temperature significantly promotes deoxygenation reaction since weighted average carbon atom number and DBE of molecules increase 28.4 % and 12.9 %, while the corresponding weighted average oxygen atom number decreases from 7.21 to 5.96 with temperature rising from 500 degrees C to 900 degrees C. Incorporating with DFT calculation, the pathways of OPAHs and SPAHs during lignin pyrolysis at high temperature are concluded: Guaiacol converts to 1-methoxynaphthalene via 4 methylation reactions, and butene firstly generates thiophene and then converts to methyl-benzothiophene. Among the reactions above, benzene ring and thiophene ring generation steps possess the highest energy barriers (436.74 kJ/mol and 446.33 kJ/mol), further illustrating higher temperature promotes the formation of OPAHs and SPAHs.
