FIELD: chemistry.
SUBSTANCE: invention can increase the efficiency of processes of nonoxidising conversion of methane due to increase in activity of W-containing zeolite catalysts. Described is the zeolite catalyst ZSM-5 for process of nonoxidising conversion of methane which has in its composition tungsten in the form of nano-sized powder, thus the content of tungsten in the catalyst is from 4.0 up to 10.0 mass %. Also the method of the preparation of zeolite catalyst for the process of nonoxidising conversion of methane is described, including modification of zeolite by tungsten as a solid, thus tungsten is introduced into zeolite in the form of nano-sized powder of the metal, obtained by the method of electrical explosion of the conductor in the environment of argon, thus the content of tungsten in the obtained catalyst is from 4.0 up to 10.0 mass %. The method of nonoxidising conversion of methane in the presence of zeolite catalyst is described.
EFFECT: obtaining of a catalyst with higher activity during conversion of methane in aromatic hydrocarbons.
