process for hydrotreating an olefinic gasoline comprising a selective hydrogenation step

摘要

The hydrotreatment of an olefinic charge to reduce the content of diolefins and acetylenes comprises selective hydrogenation with a catalyst comprising a sulfide of iron, cobalt or nickel obtained by sulfuration of the oxide form. The hydrogen used in the process may have a carbon monoxide + carbon dioxide content of 5-200 ppmv and carbon monoxide content of 1-20 ppmv.
