Abstract
The physicochemical and texture characteristics of the catalyst containing Zn-Zr / VKTs were studied in the study. It was found that the crystallinity of the Zn-Zr / VCC sample (550 С) is 89%, calcination of the zeolite at 650 С leads to a decrease in the degree of crystallinity to 81%. A further increase in the processing temperature of the zeolite does not lead to a more significant change in its crystallinity; for a sample calcined at 850 C, it also amounts to 81%, which indicates high thermal stability of zinc and zirconium aluminosilicate. The results of a study of the composition of liquid products formed during the conversion of propane on zinc and zirconium aluminosilicate samples showed that the main ones are benzene, toluene and xylene (BTK fraction), C8 C10 alkylbenzenes, as well as high molecular weight aromatic compounds, including naphthalene and its derivatives. It has been proven that with an increase in the process temperature, the degree of conversion of propane and the formation selectivity of aromatic hydrocarbons increase. At a reaction temperature of 650 C, the conversion and selectivity of the formation of aromatic hydrocarbons on a zinc and zirconium aluminosilicate sample (550 C) reach 94 and 52.8%, respectively.

Key words: Zinc, Zirconium, Catalyst, Crystallinity, Conversion, Selectivity, Propane, Aromatic Hydrocarbons.
