Clinoptilolites, including both natural clinoptilolites and those which have been ion-exchanged with metal cations such as lithium, sodium, potassium, calcium, magnesium, barium, strontium, zinc, copper, cobalt, iron and manganese, are useful for the removal of traces of carbon dioxide and water from streams of hydrocarbons having kinetic diameters of not more than about 5 Å.

A process for separating a minor proportion of carbon dioxide from a hydrocarbon having a kinetic diameter of not more than about 5A, which process comprises contacting the carbon dioxide-containing mixture with a natural clinoptilolite that has been subjected to ion-exchange with at least one metal

A process for separating a minor proportion of carbon dioxide from a hydrocarbon having a kinetic diameter of not more than about 5A, which process comprises contacting the carbon dioxide-containing mixture with a natural clinoptilolite that has been subjected to ion-exchange with at least one metal cation of the group consisting of lithium, sodium, potassium, calcium, magnesium, barium and strontium cations, thereby causing the carbon dioxide to be selectively adsorbed into the clinoptilolite.
