A process for separating a divinyl hydrocarbon from a composition mixture stream containing at least a divinyl hydrocarbon and other components, the process including (a) passing a composition mixture feed stream containing at least (i) a divinyl hydrocarbon; and (ii) a monovinyl hydrocarbon, and/or (iii) a non-vinyl hydrocarbon through a process-scale chromatography unit; wherein the process scale chromatography unit includes a ligand exchange media comprising a metal adapted to form a ligand with an olefin functionality; wherein the metal of the ligand exchange media is loaded on an adsorbent; and wherein the divinyl hydrocarbon is adsorbed onto the ligand exchange media; (b) passing a weak first elution solvent through the unit to elute the monovinyl hydrocarbon and/or the non-vinyl hydrocarbon from the unit; (c) passing a strong second elution solvent through the unit to elute the divinyl hydrocarbon product stream from the unit; and (d) recovering the divinyl hydrocarbon product stream having been separated from the other components in the composition mixture stream; and an apparatus therefor.
