HIGH-TEMPERATURE PLATFORMER Russian patent published in 2016 - IPC C10G61/02 C10G59/02 C10G35/04 

FIELD: oil and gas industry.

SUBSTANCE: invention is referred to the method for producing of aromatic compounds from hydrocarbon material flow that includes passage of flow of raw hydrocarbon material to the first reformer, which is operated at temperature from 500°C up to 540°C in order to obtain upflow from the first reformer; heating upflow from the first reformer up to the second temperature and passage of the heated flow to the second reformer, which is operated at temperature more than 540°C and wherein on inner metal surfaces of the reactor a coating of non-coked material is applied thus producing process flow containing aromatic compounds; passage of the above process flow to fractionation unit in order to produce the main flow containing C₄ and lighter hydrocarbons and residue-rich stream containing C₅ and heavier hydrocarbons; and passage of the above residue-rich stream to aromatic compounds extraction unit in order to receive in this way process flow of aromatic compounds and refined oil flow. At that the above reformers comprise catalyst containing precious metal of the VIII group at the carrier; moreover the above catalyst has reduced chloride quantity.

EFFECT: prevented increase of thermal cracking and cocking-up.
