METHOD FOR PRODUCING AROMATIC HYDROCARBON CONCENTRATE OF LIGHT ALIPHATIC HYDROCARBONS AND DEVICE FOR IMPLEMENTING IT Russian patent published in 2015 - IPC C10G35/95 C07C2/76 C07C2/86 C07C15/02 C07C2/12 C07C1/20 C10G63/02 

FIELD: chemistry.

SUBSTANCE: according to the method, the starting raw material is supplied into two successively connected reaction units - first and second with pentasil ceolite catalyst elements; the reaction units are characterised by the environment for hydrocarbon conversion into aromatic ones; the mixture produced after reaction units are divided into liquid and gas fractions; the gas fraction is supplied into an input of the first and second reaction unit. The gas fraction produced after the reaction units are divided into hydrogen-containing gas and a wide light hydrocarbon fraction containing olefins; the hydrogen-containing gas is supplied into an oxygenate synthesis unit; the formed oxygenated are supplied into an input of the first and second reaction units; the wide light hydrocarbon fraction containing olefins is supplied into an input of the first reaction unit.

EFFECT: using the present invention enables increasing the effectiveness of aromatic hydrocarbon concentrates and the alkyl benzene, particularly xylene, selectivity.
