FIELD: industrial organic synthesis. SUBSTANCE: ethylbenzene-containing feed stock flow is passed through molecular sieves to convert at least a part of passed ethylbenzene into benzene and/or xylenes. Apparatus for carrying out proposed process is also provided. EFFECT: increased degree of conversion of ethylbenzene in the flow of C8 aromatics into p-xylene. 11 cl, 1 dwg
