Abstract:
The effect of the composition of a dry mix containing molybdenum oxide, carbon, and reducing
metal (Zn or Al) on the formation of molybdenum carbides during the mechanical activation (MA) of the
mixture is studied. The phase composition of the mechanically activated samples is studied via Xray phase analysis (XPA). The optimum formulation of the mixture and the MA modes ensuring a yield of highly dispersed carbidecontaining catalyst with Mo2C + Al2O3 composition are determined. It is shown that the composition of the medium (air or argon) has no appreciable effect on the phase composition of the target product (molybdenum carbide). Catalytic testing of carbidecontaining catalyst in the reaction of hydrodes ulfurization of dibenzothiophene (DBT) is conducted, and it is established that this catalyst exhibits high activity and selectivity: at 320°C, the conversion of DBT is 92.8% and the content of cycloalkanes is 88.3%. The obtained results can be used to create an industrial zerowaste technological process for the production of molybdenum carbide
