[ What is claimed is:] [1.]1. A process for separating a diene from a mixture including said diene, said process comprising the step of:contacting said mixture with an adsorbent which preferentially adsorbs said diene, thereby producing a non-adsorbed component and a diene-rich adsorbed component, wherein said adsorbent comprises an ion-exchanged zeolite selected from the group consisting of zeolite X, zeolite Y, zeolite LSX, and mixtures thereof, said zeolite having exchangeable cationic sites, and essentially all cationic sites of said ion-exchanged zeolite contain silver cation or copper cation, and wherein the preferential adsorption occurs by .pi.-complexation.
