Abstract: The nature of the interaction between metals and a catalyst support is a crucial factor in determining the dispersed state of active component phases. In this study, a series of Ni-Mo/ZSM-23 catalysts for the hydroprocessing of plant lipids was prepared by incipient wetness impregnation. The catalysts were prepared by a different sequence of metal deposition and using various complexing agents. The catalysts were investigated by a few physico-chemical methods (TPR, UV-Vis spectroscopy, XRD, TPD-NH3, Raman spectroscopy, HRTEM). It was found that the charge of the ZSM-23 zeolite surface (positive/negative) and the type of metal ions in the impregnation solution affect the formation of phases on the support surface. The use of ammonia impregnating solutions leads to the formation of phases NiO, α-NiMoO4 and β-NiMoO4. In the case of using aqueous and citrate impregnating solutions, only the formation of NiO and β-NiMoO4 phases is observed.
