Abstract: The present invention describes a method of separating butene-2 from a C4 cut containing butene-2 and butene-1 by selective oligomerization of butene-1 to predominantly linear oligomers. Optional additional steps make it possible to separate isobutene, 1,3-butadiene as well as traces of acetylene hydrocarbons optionally present in the C4 feedstock.

Abstract: The invention relates to a catalytic composition that comprises at least one precursor of iron or cobalt, at least one organic ligand, and an activating agent that consists of at least one derivative of aluminum and at least one organic compound having at least one alcohol group and/or at least one amine group, and in which the molar ratio between the aluminum and the alcohol and/or amine group number present in said organic compound of said activating agent is preferably greater than or equal to 1. The invention also relates to a process for oligomerization of olefins using said catalytic composition.
