Abstract
Recently, simultaneous hydrotreatment of various petroleum fractions and plant feedstocks has been in demand. NiMo catalysts can be active in these processes. Therefore, supported NiMo oxide catalysts were prepared by impregnating an alumina support with Anderson’s molybdenum salt (ammonium salt of nickel heteropolymolybdate (NH4)4NiMo6O24H6) and lithium carbonate. The prepared catalysts were tested in hydrodesulfurization (HDS) of thiophene and parallel HDS/HDO (hydrodeoxygenation) of 1-benzothiophene and octanoic acid. Experimental data showed a positive effect of lithium on the parallel HDS/HDO reactions and a negative effect on the HDS of thiophene. A significant effect of lithium on the acidity and reducibility of the NiMo/Al2O3 catalyst as well as the contribution of an Anderson-type heteropolycompound was demonstrated.
