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-area
Al2O3-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.Workplace Institute of Chemical Process Fundamentals Contact Eva Jirsová, jirsova@icpf.cas.cz, Tel.: 220 390 227 Year of Publishing 2017
