METHOD OF PRODUCING GASOLINES OR CONCENTRATES OF AROMATIC COMPOUNDS WITH DIFFERENT DISTRIBUTION OF OXYGENATE STREAMS AND OLEFIN-CONTAINING FRACTION AND ADDING WATER Russian patent published in 2021 - IPC C10G35/95 

FIELD: technological processes.

SUBSTANCE: invention relates to a method of producing a liquid hydrocarbon product containing aromatic compounds. In the method, the feedstock used is three streams, the first of which includes a hydrocarbon fraction, the second stream includes an oxygenate, the third stream includes an olefin-containing fraction, wherein the olefin-containing fraction includes one or more olefins selected from a group comprising ethylene, propylene, normal butylenes, isobutylene in total amount of 10-50 wt%. Three reaction zones filled with a zeolite catalyst are used, the first stream is fed into at least one reaction zone, second flow is fed only to the last reaction zone, the third stream is fed into the first and second reaction zones, wherein water is added to the first and second reaction zones, and the product stream from the first reaction zone is fed into the second reaction zone, and the product stream from the second reaction zone is fed into the third reaction zone.

EFFECT: method enables to reduce content of heavy hydrocarbons in the product, obtain a product with a boiling point below 215 °C and resin content of less than 5 mg/100 cm³, avoid recycling of gaseous products, as well as reduce consumption of oxygenates.
