METHOD FOR DESULFURISING OLEFIN MOTOR GASOLINE

摘要

The invention concerns a process for producing gasoline with a low sulphur content and a controlled olefins content, comprising a step for oligomerizing an olefinic feed (step i), a step ii) consisting of mixing the branched olefinic gasoline produced in step i) with a gasoline rich in sulphur and olefins, a step iii) for hydrodesulphurization of said mixture, and separating the H2S formed (step iv)).
