The OPAHs from hemicellulose tar are high risk of causing cancer during thermal conversion. Therefore, the distribution of OPAHs in hemicellulose tar at different temperatures characterization via GC-MS and ESI FT-ICR MS. It is found that pyrolysis tar of xylan contain a large amount of furfural and L-glucan by GC-MS. While the ESI FT-ICR MS shows that The molecular mass of OPAHs in the tar mainly concentrate between 200 Da and 400 Da and these compounds are mostly with C atoms from 5 to 25 and DBE values from 4 to 15. Moreover, there are more decarbonylation and decarboxylation reactions with the pyrolysis temperature raise.
