Abstract: Supported iron sulphides, nickel sulphides, and iron-nickel sulphides were prepared using iron pentacarbonyl, nickel tetracarbonyl, and sulphur as precursors and γ-AlOOH as the support under different conditions, including temperature, active species and their loading sequence. Their activities for catalytic hydrocracking of di(1-naphthyl)methane (DNM) were examined at 300°C. As for the catalysts prepared at optimum temperature, Ni-S/γ-AlOOH is more active for DNM hydrocracking than Fe-S/γ-AlOOH. According to observation of SEM micrographs, Fe-Ni-S/γ-AlOOH has higher thermal stability to resist the metal particle agglomeration compared to Fe-S/γ-AlOOH.
