Method for producing gasolines or aromatic compound concentrates with different distribution of hydrocarbon, oxygenate and olefin-containing fractions to the reactor beds

A method of producing a liquid hydrocarbon product containing aromatic compounds, where three streams are used as feedstocks:

• a first stream includes a hydrocarbon fraction, a second stream includes an oxygenate, and a third stream includes an olefin-containing fraction, the method comprising:
• a. the olefin-containing fraction comprising one or more olefins from the group including ethylene, propylene, normal butylenes, and isobutylene, in total amount from 10 to 50 wt %;
• b. three reaction zones filled with a zeolite catalyst are used, thereby defining a first reaction zone, a second reaction zone and a third reaction zone;
• c. the first stream is fed to at least one reaction zone;
• d. the second stream is fed to the first reaction zone;
• e. the third stream is fed to the three reaction zones and distributed between the three reaction zones, with the mass fraction of the third stream distributed to the third reaction zone being higher than the mass fraction of the third stream distributed to each of the previous reaction zones;
• and,
• f. wherein a product stream from the first reaction zone is supplied to the second reaction zone, and a product stream from the second reaction zone is supplied to the third reaction zone.
