METHOD FOR PRODUCING BENZINES OR CONCENTRATES OF AROMATIC COMPOUNDS Russian patent published in 2021 - IPC C10G35/95 C10G3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing benzines or concentrates of aromatic compounds, in which three streams are used as raw material, first of which includes a hydrocarbon fraction, second oxygenate stream comprises the third stream comprises the olefin-containing fraction using three reaction zones filled with a zeolite catalyst, wherein the olefin-containing fraction comprises from 10 to 50 wt% olefins C₂-C₄ and from 0.5 to 8 wt% hydrogen, first stream is fed into at least one reaction zone, a second stream is fed into a first reaction zone or a third reaction zone, wherein when the second stream is fed into a first zone, distribution of the third stream between two reaction zones is 35-65 wt% / 65-35 wt%, and when the second stream is fed into the third reaction zone, the distribution of the third stream between the two reaction zones is 25-45 wt% / 75-55 wt%.

EFFECT: method enables to process hydrogen-containing streams of diluted olefins without separation of hydrogen, without recycling of gaseous products and without using internal heat exchangers, while increasing output and RON of the product.
