METHOD FOR OBTAINING HIGH OCTANE GASOLINE AND DEVICE FOR ITS IMPLEMENTATION (VARIANTS)

摘要

The present invention relates to the methods for obtaining gasoline hydrocarbons from lower olefins and can be used in the oil processing and petrochemical industries. In the embodiment of the present invention the raw material that contains at least one of the C1-C6 olefins is supplied to the reaction aera for contacting with a steady state acid catalyst based on a pentasil group ceolite, the olefins contained in the raw material are oligomerized to obtain a flow of the reaction products that contain C5+ gasoline fraction hydrocarbons, said product flow is separated to obtain gasoline and a flow of C1-C4 hydrocarbons, said C1-C4 hydrocarbons being further mixed with the flow of the raw materials, the olefins containing raw material is mixed with the benzene containing reforming gasoline fraction that boils below 85 °C, the olefins to benzene ratio in the final mixture being less than 0.5 mole/mole, and said oligomerization reaction is performed under the conditions that provide for at least partial alkylation of said benzene.
