FIELD: petrochemical processes. SUBSTANCE: process of converting aromatic hydrocarbons containing at least 9 carbon atoms into lighter aromatic hydrocarbons, including stage in which higher aromatic hydrocarbons come into contact with catalytic composition containing zeolite with bond reaction index 0.5 to 3, hydrogenation component, and, if necessary, IB group element source to give product containing xylenes, is distinguished by that catalytic composition with hydrogenation component is treated with live steam or sulfur source. EFFECT: reduced hydrogenation of aromatic hydrocarbons, increased yield of lighter hydrocarbons, and simplified process. 11 cl, 3 dwg, 6 tbl, 13 ex
