Abstract: A series of Ni-Mo/ZSM-23 catalysts with a different atomic Mo/(Ni + Mo) ratio was prepared by incipient wetness impregnation with a co-solution of salts of Ni and Mo precursors. The formation of NiMoO4 in the case of oxide catalysts was shown by XRD and Raman spectroscopy. An increase in the molybdenum content in the catalyst composition leads to a decrease in the amount of the NiO phase and an increase in the NiMoO4 phase. This correlates with changes in the activity of the reduced catalysts during the hydrotreating of a mixture of fatty acids (C16-C18) in a flow reactor at 300 °C, PH2 = 2.5 MPa, H2/FAs = 2200 m3/m3 and WHSV = 8.4 h−1. Thus, the highest conversion and iso-alkanes yield were observed in the case of NiMo-0.1 and NiMo-0.25 catalysts. With an increase in the ratio of hydrogen to raw materials to 3150 m3/m3, the highest yield of iso-alkanes is observed on the NiMo-0.4 catalyst.
