ABSTRACT:

The molecular profiles of aromatics generated through hydropyrolysis with the free (maltene) counterpart for high temperature coal tar were compared with a view to assessing the effectiveness of using molecular information for aromatics released via hydropyrolysis for PAH source apportionment studies. Results obtained indicate that the PAH profiles for asphaltene derived aromatics for all samples have similar molecular distribution since they were all obtained from asphaltene matrix where structural alterations are minimal. They are both dominated by parent PAHs
