FIELD: oil and gas industry.SUBSTANCE: invention relates to method of production of aromatic compounds out of hydrocarbons. Methods includes: regenerated catalyst supply to the first reforming unit; hydrocarbons supply to the first reforming unit operating at elevated temperature to produce the first output flow and output catalyst flow; at that the catalyst contain precious metal of VIII group on carrier and has reduced chloride content, the elevated temperature is temperature above 540°C, the reforming unit contains multiple reactors with heaters between the reactors, and end reactor operates at more higher temperature for short time of contact between the output flow from multiple reactors and catalyst; supply of the first output flow to the first fractionation plant creating overhead product containing light gases, and bottom product containing reforming product; the reforming product supply to the aromatic compounds extraction unit to produce flow of cleaned aromatic product.EFFECT: present method use increases the reforming capacity and increases the aromatic products production under lower expenses due to use of higher temperatures and simultaneous decreasing of the contact time.9 cl, 12 dwg |
