Abstract (en)
[origin: EP1602705A1] Process for the adjustment of the relative productions of petrol and gasoil from a petrol cut comprsing 4 - 15 C hydrocarbons to obtain a petrol with an improved octane index and a gasoil fraction with a high cetane index. The process is carried out in the following stages (1) membrane separation, B, of the hydrocarbon charge to obtain a selective separation of most of the linear olefins,cut beta , from the branched chain olefins, cut gamma , comprising petrols of higher octane index than the original charge; (2) (b) oligomerisation, C, of the linear olefins, beta cut, in the effluents from the membrane separation; (c) (3) separation by distillation, D, of the effluents from oligomerisation to give two cuts ; cut delta comprises hydrocarbons of final boiling points lower than 150 - 200[deg]C, and a cut , comprising hydrocarbons of initial boiling points greater than 150 - 200[deg]C; (4) (d) hydrogenation, E, of the cut to obtain a gasoil of cetane index of at least 45; (5) (e) dehydrogenation, F, of the cut delta to convert paraffins to olefins, producing a cut mu which is partly recycled to the membrane separation stage.
