METHOD OF INCREASING PRODUCTION OF AROMATIC COMPOUNDS

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.8 cl, 5 dwg, 2 tbl Изобретение относится к способу получения ароматических соединений из лигроина в качестве сырья. Способ включает: подачу потока сырья в установку фракционирования и получение вследствие этого первого потока, содержащего легкие углеводороды, и второго потока, содержащего тяжелые углеводороды; подачу первого потока в первую установку риформинга, работающую при первом наборе условий реакции, и получение вследствие этого первого потока продукта, при этом первая установка риформинга имеет вход для катализатора и выход для катализатора; подачу второго потока во вторую установку риформинга, работающую при втором наборе условий реакции, и получение вследствие этого второго потока продукта, при этом вторая установка риформинга имеет вход для катализатора и выход дл
