Abstract
The present invention relates to a method for the separation of Colefins and Cparaffins from a Chydrocarbon mixed gas including butene-1, trans-2- butene, cis-2-butene, normal butane, isobutane, etc. The method of the present invention produces Colefins with high purity by introducing a gaseous Cmixture into the adsorption tower loaded with adsorbent selectively adsorbing olefins to adsorb Colefins and to discharge Cparaffins to the outlet of the tower, desorbing Colefins adsorbed on the adsorption tower with a desorbent Chydrocarbon, Chydrocarbon, etc.), and then separating the Colefin and the desorbent by a distillation process.
