Using the method of impregnation in an excess impregnating solution and subsequent temperature treatment range 100-400 °C, synthesis γ-modified catalytic systems based on transition metals (Co, Mo) supported active aluminum oxide was carried out their physicochemical properties were studied. A distinctive feature these use polyoxometalate complexes (molybdenum blues) obtained by mechanical activation commercial molybdenum disulfide as a source molybdenum. The carrier high-temperature industrial pseudoboehmite powder AlOOH (Ishimbay Specialized Chemical Plant Catalysts LLC). This approach makes it possible to significantly simplify systems. At same time, reagents technologies used are publicly available produced territory Russian Federation scale. resulting expected be hydrotreating processes (hydrodesulfurization hydrodenitrogenation) diesel fractions. included stage obtaining adding weighed portion cobalt nitrate alcohol blue, directly solution. After impregnation, calcined at various temperatures order study genesis components effect properties. synthesized studied using methods (XRD, IR spectroscopy). It found that completely eliminate nitro group from system, least 400 °C is necessary. also shown blue can act Mo.
