PRODUCTION OF AROMATIC COMPOUNDS FROM ALIPHATIC COMPOUNDS Russian patent published in 2012 - IPC C07C2/76 C07C15/02 C07C15/04 C07C15/06 C07C15/24 B01J23/24 B01J23/34 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of converting an aliphatic hydrocarbon with few carbon atoms to high-molecular weight hydrocarbons, including aromatic hydrocarbons, involving contacting starting material containing said aliphatic hydrocarbon, with a dehydrocyclisation catalyst in conditions which are effective for converting said aliphatic hydrocarbon to aromatic hydrocarbons and obtaining an effluent stream containing aromatic hydrocarbons and hydrogen, where said dehydrocyclisation catalyst contains a metal selected from a group comprising molybdenum, rhenium and tungsten, and a molecular sieve containing ZSM-5 and where the ratio of the amount of all Bronsted acid parts in the molecular sieve to the amount of said metal is less than 0.4 mol/mol of said metal. The invention also relates to an aromatic hydrocarbon product obtained using said method and a method of producing a composition containing paraxylene, which uses an aromatic product obtained using the method described above.

EFFECT: use of the present invention reduces catalyst selectivity with respect to coke.
