Effect of Promotion Metals on the Activity of MoS2/ZrO2 Catalyst in the Parallel Hydrodesulfurization of 1-Benzothiophene and Hydrogenation of 1-Methyl-Cyclohex-1-ene.

Popis výsledku v původním jazyce

The promotion of hydrodesulfurization and hydrogenation activity of MoS2 supported on unconventional support ZrO2 (baddeleyite, SBET = 108 m2 g-1) by various novel metals was studied. The reactions were the hydrodesulfurization of 1-benzothiophene (HDS) and in selected cases, also the parallel hydrodesulfurization of 1-benzothiophene and hydrogenation of 1-methyl-cyclohex-1-ene (HYDO). The promotion metals were Co, Ni and novel unconventional promoters such as Rh, Pd, Ir, Pt, and Re. Methods of deposition of Mo and the promoters were compared using aqueous and toluene impregnation of the support leading to favorable deposition of Mo from aqueous solution of ammonium heptamolybdate in the first step followed by sulfidation and deposition of the promoters from toluenic solution of the acetylacetonates in the second step. The catalysts yielded increased HDS activities and desirable low HYDO activities. The reference conventional high-surface-areanAl2O3-supported CoMo (SBET = 325 m2 g-1) and NiMo (SBET = 253 m2 g-1) catalysts still yielded about 2-fold HDS activities than the newly studied ZrO2- supported catalysts.
