Abstract
Unsaturated compounds are separated from liquid hydrocarbon mixtures by adsorbing the unsaturated compounds on a macroporous cation exchange resin and desorbing the unsaturated compounds with a mononuclear aromatic compound.
Claims13
A process for the separation of unsaturated hydrocarbon compounds from a liquid, paraffin-rich hydrocarbon mixture comprising:
- (a) contacting the hydrocarbon mixture with a dehydrated, macroporous cation exchange resin in the form of a metal salt whereby the unsaturated compounds are adsorbed by the resin,
- (b) contacting said dehydrated macroporous cation exchange resin containing adsorbed unsaturated compounds with a mononuclear aromatic hydrocarbon at a temperature of 50.degree. to 150.degree. C. whereby the adsorbed unsaturated compounds are desorbed.
