Abstract: FIELD: rubber production.SUBSTANCE: invention relates to the field of obtaining widely used monomers for the production of synthetic rubbers, and more specifically to a method for producing styrene by ethylbenzene dehydrogenation. A method for producing a porous ceramic catalytic converter is proposed by self-spreading high-temperature synthesis from an aluminum-containing charge containing wt.%: α-Al2O3- 85-95; MgO - 1-5; SiC - 5-9, with the formation of a porous ceramic tube, in which an additional intermediate layer of γ-Al2O3is formed on the surface of the tube by the sol-gel method. After that, the catalytically active components are applied, successively impregnating the surface of the tube with aqueous solutions of potassium carbonate and cerium nitrate. Then, water-alcohol solutions of the NBu4ReO4and (NH4)6W12O39·H2O complexes are separately applied, and the tube is calcined in the air current stepwise increasing the temperature to obtain a catalytic converter of ethylbenzene dehydrogenation into styrene. A method for producing styrene is proposed by ethylbenzene dehydrogenation in the presence of the resulting catalytic converter, by mixing ethylbenzene vapors with water vapors in a ratio of 1:12-16. Dehydrogenation is carried out at a temperature of 575-625°C and a volumetric feed rate of 1.2-1.6 h-1.EFFECT: increase in the production capacity of styrene in the process of ethylbenzene dehydrogenation per unit of time per gram of catalyst to 7.23 g/h*gact. comp., which is ~23 times greater than in traditional industrial reactors, with lower costs for the volume of water supplied and the loading of the catalyst used, reducing the degree of carburization of the converter for 6 hours of operation for no more than 5 wt.%.2 cl, 1 dwg, 4 tbl, 22 ex
