A new precursor for synthesis of nickel-tungsten sulfide aromatic hydrogenation catalyst

The unsupported NiWS-catalyst was obtained from the precursor [Ph3S]2Ni(WS4)2 in a hydrocarbon medium (in situ) for hydrogenation bicyclic aromatic compounds. The precursor [Ph3S]2Ni(WS4)2 and the catalyst prepared on its basis were studied by the X-ray diffraction and X-ray absorption methods, XPS and TEM. It was found that the new catalyst formed in situ contains tungsten sulfide and nickel sulfide nanophases. Tungsten sulfide, which has a layered structure, partially forms an insertion compound with nickel that enters between the WS2 layers and bonds covalently to sulfur. The proposed catalyst has proved to be active in the hydrodearomatization processes of model aromatic compounds (naphthalene, methylnaphthalenes) and exhibited the maximum selectivity with the formation of decalins compared to other earlier studied catalysts formed from other precursors in the reaction medium.

Catalytic activity of in situ synthesized MoWNi sulfides in hydrogenation of aromatic hydrocarbons

MoWNi–sulfide catalysts were obtained in situ by thermal decomposition of metal–polymer precursors based on the copolymers of polymaleic anhydride in a hydrocarbon raw material. The activity of the synthesized catalysts in hydrogenation of bicyclic aromatic hydrocarbons was studied, and the composition and structure of active phase nanoparticles were determined.

The hydrogenation of aromatic-naphthalene with Ni2P/CNTs

Ni2P/CNTs was synthesized using an impregnation method. XPS revealed that CNTs could affect the electronic properties of bulk Ni2P. The catalyst shows superior activity for HYD of naphthalene with a conversion of 99%, and demonstrates superior tolerance towards potential catalyst poisons, which is higher than Ni/CNTs with a conversion of 89%.
