Hydrofining of light cycle oil over in situ synthesized nickel–tungsten sulfide catalysts

AbstractA comparative study of nickel-tungsten sulfide catalysts for hydrodearomatization prepared in situ in a reaction medium by different methods (from a [BMPip]2Ni(WS4)2 precursor in a hydrocarbon or in an ionic liquid, from a suspension of nickel and tungsten salts formed from inverted emulsions in hydrocarbons, or from oil-soluble precursors) has been carried out. It has been found that the use of the oil-soluble precursors makes it possible to reach a high degree of sulfidizing of the active phase and a high degree of its promotion by nickel at a small size of the active phase particles. The resulting catalyst can be applied to the hydrogenation of both the naphthalene and substituted methylnaphthalenes (2-methylnaphthalene, 2,6-dimethylnaphthalene, 2,3-dimethylnaphthalene, and 2,3,6-trimethylnaphthalene) with the high selectivity for decalins and to the hydrodearomatization of light cycle oil with the complete removal of di- and polycyclic aromatic compounds.

The hydroprocessing of substituted naphthalenes and light cycle oil (LCO) over bimetallic Ni-W-S and Ni-Mo-S catalysts that were obtained by decomposition of [N(n-Bu)4]2[Ni(MeS4)2] (Me = W, Mo) complexes in situ in the pores of mesoporous aromatic frameworks (PAFs) during the reaction, was studied. The promotion of acid-catalyzed processes by PAF-AlCl3, synthesized by impregnation of a PAF with AlCl3 from its toluene solution, was investigated. It has been found that Ni-W-S catalytic systems were more active in the hydrodearomatization reactions, while Ni-Mo-S catalytic systems were more active in hydrodesulfurization and hydrocracking reactions. The introduction of sulfur into the reaction medium enhanced the activity of the catalysts and the presence of PAF-AlCl3 led to an acceleration of the hydrocracking processes.
