FIELD: petrochemical processes.
SUBSTANCE: catalytic system, lower olefin, oligomerization medium are first provided. Reaction of lower olefin proceeds in presence of chromium-containing catalytic system to form product stream comprising higher olefinic product and rest of catalytic system, which are dispersed in process medium. Product is treated with suppressing substance, which is aliphatic secondary amine, alcohol, or combination thereof.
EFFECT: reduced corrosion of process equipment.
