METHOD FOR DESULFURISING OLEFIN MOTOR GASOLINE

摘要

The invention relates to a method for producing a motor gasoline having a low-sulphur content and an olefin controlled content comprising an olefin feed oligomerisation stage (stage i), a stage (ii) consisting in mixing a branched olefin motor gasoline produced at the stage (i) with a sulphur and olefin-rich motor gasoline, a stage (iii) for the hydrodesulfurisation of said mixture and a stage (iv) for separating the thus formed H₂S.
