Fe–S/γ–Al2O3 was prepared by thermally decomposing Fe(CO)5 onto γ–Al2O3 and subsequent sulphurisation with sublimed sulphur in a magnetically stirred autoclave and used as the catalyst for catalytic hydroconversion (CHC) of Lingwu bituminous coal (LBC). Non–catalytic hydroconversion (NCHC) and CHC of LBC were conducted in cyclohexane under 5 MPa of initial hydrogen pressure at 300°C. The reaction mixtures were extracted with petroleum ether and analysed with a gas chromatographyγmass spectrometer. The results show that Fe–S/γ–Al2O3 significantly catalysed the formation of hydroarenes, arenes and arenols and completely removed 2,5–dimethylthiophene from LBC.
