Method for removing catalyst from an olefinic oligomerization product, comprising the steps of oligomerizing one or more olefins in presence of a BF3 cocatalyst complex, and distilling the oligomerization product while separating vaporized BF3 cocatalyst complex, said distillation step comprising, simultaneously to said separation of BF3 cocatalyst complex, a separation of vaporized unreacted monomer from a bottom product which becomes substantially free from BF3 cocatalyst complex.
La présente invention concerne un procédé d'élimination d'un catalyseur contenu dans un produit de polymérisation oléfinique. Ledit procédé consiste à oligomériser une ou plusieurs oléfines en présence d'un complexe cocatalyseur-BF¿3?, à distiller le produit d'oligomérisation tout en séparant le complexe cocatalyseur-BF¿3? vaporisé. La distillation consiste, simultanément à la séparation du complexe cocatalyseur-BF¿3?, en une séparation du monomère vaporisé n'ayant pas réagi dans le produit de fond qui devient alors essentiellement exempt du complexe cocatalyseur-BF¿3?.
