METHOD OF SEPARATING BUTENE-2 FROM A C4 CUT CONTAINING BUTENE-2 AND BUTENE-1 BY SELECTIVE OLIGOMERIZATION OF BUTENE-1

摘要

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.
