ABSTRACT
Free and asphaltene
derived samples of high temperature coal tar (HTCT 1 and 2 respectively) from
the Kopper plant in Scunthorpe, North Lincolnshire were analyzed for polycyclic
Aromatic Hydrocarbons using gas chromatographic-mass spectrometry (GC-MS). The
concentrations of the individual PAHs ranged from 1.2 mg/g-98 mg/g with a mean
concentration of 390.7 mg/g ± 23.05 mg/g. The study showed a higher
concentration of the high molecular weight PAHs for
both free and asphaltene derived low temperature coal tar implying that the
asphaltene derived can be used for correlation and source apportionment studies
where the free has been altered.
