FIELD: chemistry.
SUBSTANCE: present invention relates to a device and a method of producing aromatic hydrocarbons by combining naphtha and methanol. Device for producing aromatic hydrocarbons by combining naphtha and methanol is characterized by the fact that it contains a reactor for aromatization of light hydrocarbons and a reactor for producing aromatic hydrocarbons from combined naphtha and methanol. Reactor for aromatization of light hydrocarbons is intended for introduction of raw materials and high-temperature catalyst, and at least one outlet of the reactor for aromatisation of light hydrocarbons is connected to the reactor for producing aromatic hydrocarbons from combined naphtha and methanol for transporting the catalyst and the obtained gaseous aromatization product of light hydrocarbons to the reactor for producing aromatic hydrocarbons from the combined naphtha and methanol. Reactor for producing aromatic hydrocarbons from combined naphtha and methanol is designed to introduce naphtha and methanol and allow contact of naphtha with a catalyst from the reactor for aromatization of light hydrocarbons to form a gaseous product stream containing BTX, after reaction and subjecting methanol to a methylation reaction with benzene and toluene in a gaseous product stream to form p-xylene.
EFFECT: use of the invention increases output of aromatic hydrocarbons; heat generated in situ is used; the rate of reaction and output of aromatic hydrocarbons is increased.
