FIELD: chemistry.
SUBSTANCE: invention relates to a method for transalkylation of a crude stream containing C7, C9, C10 and C11+ aromatic hydrocarbons to obtain a transalkylation product stream with high concentration of C8 aromatic compounds compared to concentration thereof in the crude stream. The method involves bringing a crude stream, in transalkylation conditions, into contact with a catalyst containing aggregated material UZM-14, which contains globular aggregates of crystallites, having a mordenite-type skeleton with channels of 12-member rings, mesopore volume of at least 0.10 cm3/g and average length of crystallites parallel to the direction of channels of 12-member rings equal to or less than 60 nm.
EFFECT: disclosed method enables to obtain xylenes with high output, wherein the catalyst is active and stable during the transalkylation process.
