Abstract


Heteroatom-containing species in the coal liquid oils (CLO) were identified and
quantified by the aid of gas chromatography with atomic emission detector (GCAED).
Four different CLOs from different rank coals, processes and cut points
were investigated in the present study. Thiophene and its derivatives were found
to be the major sulfur compounds, pyridines and anilines, and phenols were the
major nitrogen and oxygen compounds, respectively in the oils of boiling range
<300oC). An oil of boiling range (300–420oC) carried more
dimethyldibenzothiophenes and benzoquinolines. The correlation between feed
coal and liquid product was discussed in terms of the compositions of
heteroatomic compounds.
