A manufacturing process for .alpha.-olefins using certain iron containing ethylene oligomerization catalysts together with alkylaluminum cocatalysts, in which using a low ratio of Al:Fe in the process results in a lowered formation of undesired polyethylene waxes and polymer. This results in less fouling of the process lines and vessels in the manu-facturing plant.

L'invention concerne un procédé de fabrication d'.alpha.-oléfines utilisant certains catalyseurs d'oligomérisation d'éthylène contenant du fer conjointement avec des cocatalyseurs d'alkylaluminium. Dans ce procédé, un faible rapport Al:Fe implique une formation réduite de polymère et de cires de polyéthylène indésirables, ce qui contribue à limiter l'encrassement des cuves et des conduites de traitement dans l'usine de fabrication.
