ABSTRACT:
A process for separating 1,3-butadiene from a feed mixture comprising 1,3-butadiene and at least one other C.sub.4 hydrocarbon. The process comprises contacting the feed, in liquid phase at adsorption conditions, with an adsorbent comprising activated or molecular sieve carbon which selectively adsorbs the 1,3-butadiene. The feed is then removed from the adsorbent and the 1,3-butadiene recovered by desorption at desorption conditions with a desorbent material comprising a hydrocarbon. The feed mixture and desorbent material have boiling points of at least 5.degree. C. difference.
