Hydrodesulfurization of benzothiophene catalyzed by molybdenum sulfide cluster encapsulated into zeolites
- Univ. of Tokyo (Japan); and others
A cationic molybdenum sulfide cluster [Mo{sub 3}S{sub 4}(H{sub 2}O){sub 9}]{sup 4+} with incomplete cubane-type structure and a cationic nickel-molybdenum mixed sulfide cluster [Mo{sub 3}NiS{sub 4}Cl(H{sub 2}O){sub 9}]{sup 3+} with complete cubane-type structure were introduced into zeolites NaY, HUSY and KL by ion exchange. Stoichiometry of the ion exchange was well established by elemental analyses. The UV-visible spectra and EXAFS analysis data exhibited that the structure of the molybdenum cluster remained virtually intact after ion exchange. MoNi/NaY catalyst prepared using the molybdenum-nickel sulfide cluster was found to be active and selective for benzothiophene hydrodesulfurization.
