Improved performance of Fe–Ni–S/γ–AlOOH for catalytic hydrocracking of di(1–naphthyl)methane

0
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.
