The analysis of scientific publications and patents devoted to mechanochemical synthesis of inorganic supports and catalysts of oil processing processes: cracking, reforming, hydrotreating and hydrocracking is carried out. It s shown that the introduction of mechanical activation into the technological process of synthesis of inorganic supports and catalysts, as a rule, leads to an increase in catalytic activity and selectivity.

... oxides, which are precursors of sulfide nickel-molybdenum hydrotreating catalysts, were considered. It is shown that under conditions of mechanical activation, it is possible to obtain a nickel-molybdenum highly active and thermostable β-NiMoO4, in which Mo is in a tetrahedral conformation. The technology of obtaining highly dispersed carbide-containing catalysts developed using the IHCP SB RAS using the method of mechanical activation is described. The texture and morphology of synthesized highly disperse massive carbide-containing catalysts are considered. It is shown that the size of active particles is 2–5 nm. Model catalytic tests have been carried out and it has been established that carbide-containing highly disperse catalysts exhibit high catalytic activity in the model hydrodesulphurization reaction of dibenzothiophene.
