FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst for converting methanol into aromatic hydrocarbons, method of producing said catalyst and method of converting methanol into aromatic hydrocarbons. Catalyst contains 85 to 99 parts by weight of zeolite ZSM-5, from 0.1 to 15 parts by weight of element M1, which is least one element selected from a group consisting of Ag, Zn and Ga, and from 0 to 5 parts by weight of element M2, which is at least one element selected from a group consisting of Mo, Cu, La, Ce and P, Co, wherein total specific surface area of catalyst is in range of 350–500 m²/g, and specific surface area of micro pores is within range of 200–350 m²/g. Method involves following steps: step I: mixing template agent I, an inorganic acid, silicon source, aluminium source, water, soluble compound of element M1 and, optionally, soluble compound of element M2 to obtain a mixture, converting mixture into gel with subsequent holding and drying of gel to obtain amorphous mixed silicon-aluminium mixed oxide precursor; step II: mixing silicon-aluminium mixed oxide precursor obtained at step I, with a crystal seed and binding agent, moulding and drying mixture to produce a moulded semi-finished product; and step III: crystallisation followed by calcination of moulded semi-finished product obtained at step (II), to obtain said catalyst. Catalyst is characterised by high values of total specific surface area, specific surface area of micro pores and micropore volume.

EFFECT: results of reaction for synthesis of aromatic hydrocarbons from methanol using a catalyst, provided in present invention, demonstrated good catalytic activity.
