Abstract
The samples of MoS2 with added small amounts of polar liquids were synthesized for the first time by means of soli-phase mechanical activation of commercial molybdenite. Physicochemical characteristics of the catalysts are discussed that have been measured by means of sedimentation analysis, XSA, XPES, TEM, thermal analysis. The high activity of the catalyst with small added amount of methanol was discovered in the model reaction of dibenzothiophene hydrogenolysis. It is demonstrated that the level of detect content does not determine the hydrodesulphurising ability of monocatalysts in the model reaction. Interconnection between the physicochemical characteristics of the catalysts and their activity in the model reaction was studied. Conclusions concerning the reaction routes were made on the basis of analysis of the composition of hydrodesulphurising agents by means of gas chromatography-mass spectrometry.
