Molecular species in Tanito Harum coal liquid of different fractions were identified by the aid of gas chromatography with atomic emission detector (GC-AED). Two different forms of coal liquids oils as liquefied and its hydrotreated ones were analyzed in the present study. Thiophenes and benzothiophenes were found to be the major sulfur compounds. Pyridines and anilines, and phenols were the major of nitrogen and oxygen compounds, respectively. Sulfur species were completely removed by the present hydrotreatment conditions, whereas refractory nitrogen species still remain in hydrotreated gas oil. Among such species, we identified new species such as C_<11>H_<19>N and C_<14>H_<23>N, respectively, according to the elemental analyses by GC AED and molecular weight by GC-MS, which are believed to be produced during hydrotreatment.
