Abstract: Natural and associated petroleum gases are the most important potential sources for production of valuable petrochemical products including those of organic synthesis. A development of one-step catalytic process for conversion of methane, the main component of natural and associated gases, into aromatic compounds is important to solving the problem of their rational use and environmental protection. Dehydroaromatization of methane is effective due to the use of catalytically active high silica zeolites modified with transition metal ions. Regarding that the zeolite H-ZSM-5 containing molybdenum exhibit higher CH4 conversion and selectivity to benzene than other type’s zeolites. Generally, the catalysts are produced via zeolite impregnation by metal salt solution or via mechanical mixing of a zeolite with a metal oxide. The purpose of the present investigation is to examine the influence of different Mo forms and the method for their introduction into the zeolite matrix on acidic properties, catalytic activity and stability of Mo/ZSM-5 catalysts in the process of methane dehydroaromatization (DHA) under non-oxidative conditions. Using high-resolution transmission electron microscopy (HRTEM) and energy-dispersive X-ray (EDX) spectroscopy, we studied the nature and distribution of active sites on the surface of Mo/ZSM-5 catalysts.
