Abstract:
The liquid product derived from coliquefaction of Shendong coal and sawdust was separated into several groups by employing open-column technique. And the heteroatom-contained compounds were isolated and analyzed with Varian GC/MS 4000. The results show that the heteroatom-contained can be determined in F
2 to F
6 fractions, and the phenol and its derivatives from F
2 predominate the oxygen-contained compounds. The aliphatic esters and aromatic esters subsequent dominate the oxygen-contained compounds from F
3, F
4 and F
6. The minority of Nitrogen- and Sulphur-contained compounds are quinoline and sulfides.
