METHOD OF INCREASING PRODUCTION OF AROMATIC COMPOUNDS Russian patent published in 2015 - IPC C10G63/04 C10G61/02 C10G59/02 C10G35/04 C07C4/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of obtaining aromatic compounds from ligroin as a raw material. The method includes: supply of the raw material flow into a fractioning installation and with obtaining the first flow, which contains light hydrocarbons, and the second flow, which contains heavy hydrocarbons; supply of the first flow into the first reforming installation, which works under the first set of reaction conditions, with obtaining the first product flow, with the first reforming installation having an input for the catalyst and an output for the catalyst; supply of the second flow into the second reforming installation, which works under the second set of the reaction conditions, with obtaining the second product flow, with the second reforming installation having an input for the catalyst and an output for the catalyst, in which the first set of the reaction conditions includes the first reaction temperature, and the second set of the reaction conditions includes the second reaction temperature, and the first temperature of the reaction is higher than the second reaction temperature, and in which the second pressure is lower than 580 kPa; supply of the second product flow into the first reforming installation and obtaining the first product flow; supply of the catalyst from the regenerator into the second reforming installation; supply of the catalyst from the second reforming installation into the first reforming installation; and supply of the first product flow into the installation for the separation of aromatic compounds, with the claimed catalyst containing a noble metal of VIII group on a carrier.

EFFECT: obtaining aromatic compounds from ligroin.
