Abstract
Polymerization grade butene-1 is recovered from a C4 stream containing butene-1, isobutane, n-butane, butenes-2, reduced amounts of C3 and C5 hydrocarbons, butadiene and acetylenic hydrocarbons, by submitting the stream to the following stages: separation by means of distillation (18) of the isobutane (5), separation from residual stream (6), by distillation (19), of butene-1 (7) at a purity level of from 80% to 95%, selective hydrogenation (17) of the butadiene and of the acetylenic derivatives contained in the stream of butene-1 at the given purity level, and distillation (20) of the hydrogenated stream (10) with separation of polymerization grade butene-1 (13). Isobutene can be removed from the C4 stream prior to its being thus treated by conversion into an ether (16). <IMAGE>
