This invention relates to a process for selectively adsorbing and recovering an organic gas containing unsaturated linkages from a mixture of gases over a cuprous ion-exchanged zeolite of the faujasite type. The process is particularly suited for adsorbing gases such as carbon monoxide and ethylene over a zeolite having a silica to alumina molar ratio from 1.5 to 3.0.

A pressure swing process for selectively absorbing and recovering an organic gas containing unsaturated linkages from a mixture of gases by passing the mixture over a zeolite ion-exchanged with cuprous ions characterized in that the zeolite has a faujasite type structure and has a silicon to aluminum atomic ratio from 1.2-3 and wherein the zeolite has been granulated after being copper ion-exchanged and prior to contact with the gaseous mixture. A pressure swing process for selectively absorbing and recovering an organic gas containing unsaturated linkages from a mixture of gases by passing the mixture over a zeolite ion-exchanged with cuprous ions, characterised in that the zeolite has a faujasite type structure and has a silicon to aluminum atomic ratio from 1.2-3; and wherein the zeolite is prepared by the following series of steps: initially exchanging the zeolite by treatment with cupric ions, granulating the initially exchanged zeolite so that the granulated zeolite has a particle size greater than 1 mm, and reducing the granulated zeolite containing cupric ions to said cuprous ion exchanged zeolite, prior to contact with the gaseous mixture.
