Реферат: Co2Mo10/Cox/Al2O3 catalysts were synthesized from the ammonium salt of [Co2Mo10O38H4]6− anion supported on alumina modified with various amount of cobalt sulphide. The catalysts were analyzed using X-ray powder diffraction, N2 physisorption, high-resolution transmission electron microscopy and X-ray photoelectron spectroscopy. The catalysts were tested in the hydrodesulphurization (HDS) of dibenzothiophene and 4,6-dimethyldibenzothiophene and the hydrodenitrogenation (HDN) of quinoline. The presence of cobalt sulphide particles on the catalysts surface affects catalytic properties significantly, whereas the structure of the active phase remains constant. The catalytic activity, selectivity and turnover frequency during the HDS and HDN reactions depend on the amount of modifier (cobalt sulphide) in the Cox/Al2O3 supports and can be explained by hydrogen spillover effect. The model of HDS reaction over Co2Mo10/Cox/Al2O3 catalyst involving hydrogen spillover was established. The obtained results allow us to focus attention on the role of the cobalt sulphide particles on the surface of hydrotreating catalysts.
