Abstract:
Procedures for the synthesis of massive molybdenum carbide by the mechanical activation of a mixture of MoO3, commercial carbon, and Zn in air and the synthesis of the supported carbidecontaining catalyst Mo2C/C by the mechanical activation of commercial carbon impregnated with a 16% aqueous solution of ammonium paramolybdate in an inert atmosphere were developed for the first time. With the use of a set of physicochemical methods, the metal contents, particle sizes, specific surface areas, and phase compositions of the mechanically activated composites were determined. The structure of the carbidecontaining supported catalyst was studied by electron microscopy, and its acidic properties were studied by the temperatureprogrammed desorption of ammonia; catalytic tests in the model reactions of dibenzothiophene
(DBT) and alkane aromatization were performed. It was found that the Mo2C/C catalyst exhibited high activity in these reactions: the conversion of DBT at a contact time of 3–6 h was 80–85%. The conversion of nheptane at a contact time of 2 h was 31.2%, and 100% toluene was the reaction product. An increase in the contact time to 6 h led to a decrease in the conversion of nheptane to 1.3%, and to 47% C6–C7 cycloalkanes
were present in the reaction products. The results of this work are indicative of the high catalytic activity of the Mo2C/C catalyst obtained by mechanical activation.
