ResumoThe molybdenum sulfide cluster [Mo3S4(H2O)9]4+ (1) and the nickel-molybdenum bimetallic sulfide cluster [Mo3NiS4Cl(H2O)9]3+ (2) were incorporated into zeolites NaY, HUSY, KL, NaMOR and NaH β by aqueous ion-exchange. The catalysts supported on KL and NaMOR exhibited a higher activity for hydrodesulfurization (HDS) of benzothiophene than catalysts supported on other zeolites. Nickel incorporation into Mo/zeolite catalysts enhanced the HDS activity remarkably. Teh catalysts prepared by ion-exchanging zeolites with 2 were more active in the HDS reaction than the catalysts prepared by ion-exchanging 1/zeolite with nickel nitrate solution; the presence of the MoSNi linkage in 2 will be effective for producing active HDS species.
