FIELD: chemistry.

SUBSTANCE: described is a method of preparing a catalyst for producing aromatic hydrocarbons by converting hydrocarbon gases, which involves depositing molybdenum on a support which is zeolite HZSM-5, via impregnation thereof with an aqueous solution of a molybdenum salt, followed by calcination in air at temperature of 500-600°C, wherein the zeolite HZSM-5 in powder form is first subjected to dealumination via thermal-steam treatment in an air current with steam partial pressure of 10-60 kPa at temperature of 450-550°C, and the obtained zeolite HZSM-5 with total content of molybdenum of 2-5 wt % is mixed with an inert material which actively absorbs microwave energy, based on a metal oxide or carbide, with weight ratio of the components of 2-4:1, respectively. Disclosed is a method of producing aromatic hydrocarbons in the presence of the catalyst obtained using the method described above.

EFFECT: low power consumption while simplifying implementation of the process using an active catalyst.
