FIELD: chemistry.

SUBSTANCE: invention relates to a method for obtaining a catalyst composition and a method for converting alkylaromatic hydrocarbons, including producing a catalyst composition by the specified method and bringing the mentioned feedstock into contact with the specified catalyst composition The method for obtaining the catalyst composition includes: (a) obtaining a carrier containing (i) mordenite in amount ranging from 30 to 70% by wt. per the total weight of the carrier, (ii) zeolite of ZSM-5 type in amount ranging from 15 to 60% by wt. per the total weight of the carrier; and (iii) an inorganic binder in amount ranging from 10 to 40% by wt. per the total weight of the carrier; (b) introducing molybdenum into the carrier in amount ranging from 2 to 9% by wt. in the form of metal per the total weight of the catalyst composition and affecting the carrier treated in this way with a temperature from 100 to a maximum of 300°C ; and (c) introducing platinum in amount from 0.005 to 0.5% by wt. into the molybdenum-containing carrier obtained at stage (b) per metal relatively to the total weight of the catalyst composition, and affecting the carrier treated in this way with a temperature from 300 to a maximum of 600°C.

EFFECT: high degree of purity of benzene, high yield of benzene and high product selectivity at commercially profitable reaction temperatures.
