Disclosed is an olefin containing stream from an oxygenate to ol efin process, and a process for making olefin dimer and oligomer product from the olefin containing stream using a nickel based oligomerization catalyst. The dimer/oligomer product is optionally converted to haydroformylated product. The olefin containing stream that is used to make the higher olefin product has low levels of impurities including nitrogen, sulfur and/or chlorine.

L'invention concerne un flux contenant des oléfines mis en contact avec un composé oxygéné afin d'obtenir un produit oléfinique , et un procédé de production de produit dimère ou oligomère oléfinique à partir dudit flux contenant des oléfines à l'aide d'un catalyseur d'olégomérisation à base de nickel. Le produit dimère/oligomère est éventuellement transformé en un produit hydroformylé. Le flux contenant des oléfines utilisé pour produire le produit oléfinique présente de faibles niveaux d'impuretés, notamment en azote, en soufre et/ou en chlore.
