Abstract (en)

[origin: EP1602637A1] A transformation process applicable to charges containing 4 - 15 carbon olefins comprises membrane separation of linear and branched olefins, oligomerization of the linear olefins, separation into light and heavy cuts, and hydrogenation of the heavy cut to obtain a gasoil of high cetane index. The process involves stages of (1) membrane separation of the charge producing a cut (beta ) containing mainly linear olefins and a cut (gamma ) comprising mainly branched chain olefins i.e. a high octane petrol; (2) treatment of the linear olefins (beta ) in moderate oligomerization conditions; (3) separation by distillation of the effluents from the oligomerization to obtain a light cut, delta (comprising hydrocarbons of final distillation point less than 150 - 200[deg]C) and a heavy cut ( ) (comprising hydrocarbons of initial distillation greater than 150 - 200[deg]C); (4) and hydrogenation of the heavy cut ( ) to obtain a gasoil of high cetane index, at least 35 and preferably greater than 45.
