Abstract:
The molecular profiles of aromatics generated through
hydropyrolysis with the free (maltene) counterpart were compared,
with a view to assessing the effectiveness of using molecular
information for the aromatics released via hydropyrolysis for
PAH source apportionment studies. The results obtained from GC-MS
total and selected ion molecular profiles of free and bound
aromatics for Nigeria crude oil. The free aromatics have been
heavily biodegraded whereas the bound is preserved. Aromatics
released via hydropyrolysis are generally alkylated.
Key words: Crude oil, aromatics, hydropyrolysis
