Abstract
For the first time, an approach to a single-stage manufacture of bulky sulphide catalysts using a solid-phase method performed by means of the mechanical activation of a mixture consisting of coarse molybdenum disulphide and cobalt powders, in the presence of detonation nanodiamonds is described. An effect exerted by the mechanical treatment duration, ratio between the initial components and nanodiamonds on the process of nanofragmentation of molybdenum disulphide and activity of catalytic systems obtained in the model reaction of DBT hydrodesulphurisation has been studied.
