“…Therefore, the selection of Ni precursors is considered as one of the most important factors for the preparation of Ni-based catalysts. As reported in previous studies, the reduction degrees and dispersion of nickel, and the particle sizes of Ni/Al 2 O 3 catalysts closely depended on the anion size and property of nickel precursors [98][99][100].…”

A number of catalysts made of Ni particles of different size distributions supported on a hierarchical beta zeolite (Ni/h-beta) were prepared and tested in the hydroreforming of low-density polyethylene (LDPE) thermal cracking oils. The materials were prepared by identical impregnation method but using different nickel precursors: chloride, nitrate, acetylacetonate, and tris(ethylenediamine) nickel(II) chloride (TEDAN). A variation in the Ni particles size distribution was obtained depending on the metal precursor, whereas no significant differences in the acidic properties were detected. Ni nitrate and acetylacetonate resulted in smaller and more dispersed particles, thus closer to the acid sites, driving to higher hydrogenation and hydrocracking activities. In contrast, Ni TEDAN and chloride led toward larger nickel particles which prevented intermediate species to be rapidly hydrogenated and so favored the production of aromatic and branched hydrocarbons. Hence, the catalyst coming from Ni nitrate produced 25 wt % iso-paraffins and 71% light products (C 1 −C 12 ), while the material prepared with Ni chloride produced 35% iso-paraffins and 60% light products.
