Characteristics of nitrogen-containing aromatic compounds in coal tars during secondary pyrolysis

Comparative mutagenicity assessment of aerosols in emissions from biofuel combustion

“…For example, trends in ring-number distributions of polycyclic aromatic compounds (PAC) and nitro-PAC during coal pyrolysis (Yu et al, 1998(Yu et al, , 1999 indicated that neutralization, polymerization and ring rupture were predominant at different stages of pyrolysis. As explained previously both fuel and stove parameters would affect pyrolysis and combustion in biofuel stoves.…”

Investigation of pyrolysis behavior of carbofuran by pyrolysis-gas chromatography–mass spectrometry

“…Based on the contents variation of the pyrolysis components versus the temperature, the radical chain mechanism, and the reactions of the intermediate radicals [13,15,[27][28][29][30][31][32], the pyrolysis mechanism of carbofuran can be described as followings.…”

“…Fig. 9 shows that some of the radicals can be interacted and transformed as new molecules or radicals [30][31][32]. The PAHs, the mono aromatics, and their oxygenous or nitrogenous derivatives can be produced in this pathway.…”

Comprehensive database of Manufactured Gas Plant tars. Part C. Heterocyclic and hydroxylated polycyclic aromatic hydrocarbons

“…While in general PANHs are present in lower concentrations than their non‐substituted PAH analogues, their higher water solubility leads to a higher potential bioavailability and increased potential toxic effects within the environment . PANHs are highly stable relative to neutral PAHs and can persist through severe thermal conditions; they are thus compounds of possible toxicological interest …”
