Abstract: The present invention relates to an oligomerization process implemented in a gas/liquid reactor comprising a headspace recycle loop. The process more particularly relates to the oligomerization of ethylene to linear alpha-olefins such as 1-butene, 1-hexene, 1-octene or a mixture of linear alpha-olefins.
