Resumo
Nickel–tungsten sulfide catalysts synthesized by two methods—conventional supporting of active components and in situ synthesis in the reaction medium—have been characterized by a complex of physicochemical analysis methods. The catalysts have been compared with respect to their activity in the hydrocracking of vacuum gas oil (VGO) in a batch mode under conditions of varying temperature (380–400°C), reaction time (3–10 h), and zeolite (4–8 wt %) and NiW content (0.85–1.7 wt %). It has been shown that the in situ synthesized catalyst is superior in the hydrocracking and hydrodesulfurization of VGO owing to the accessibility of active catalyst sites.
