Abstract: 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.
