METHOD OF INCREASING PRODUCTION OF AROMATIC COMPOUNDS Russian patent published in 2015 - IPC C10G35/04 C07C4/06 C07C15/02 C10G59/06 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing aromatic compounds from a hydrocarbon feed stream. The method includes steps of: directing the hydrocarbon feed stream into a separation apparatus to obtain a light process stream having low concentration of endothermic hydrocarbon components, and a heavy process stream having a higher concentration of endothermic components; directing the light process stream into a first reforming apparatus, having a first operating temperature higher than 540°C, to obtain an output stream from the first reforming apparatus; directing the heavy process stream into a second reforming apparatus, having a second operating temperature lower than 540°C, to obtain an output stream from the second reforming apparatus; and directing the output stream from the first reforming apparatus and the output stream from the second reforming apparatus into an apparatus for separating aromatic hydrocarbons to obtain a stream of the purified product - aromatic hydrocarbons and an aromatic hydrocarbon-impoverished raffinate stream; wherein the first reforming apparatus and the second reforming apparatus contain the same catalyst.

EFFECT: use of the present method increases output of aromatic hydrocarbons.
