Abstract
Abstract This invention relates to an adsorption material for olefins, a gas chromatography column and a method for removing olefins from a mixture with saturated hydrocarbons by gas chromatography. The adsorption material according to the invention is a thermostable, macroporous resin having strongly acid ion exchange groups to which silver ions are linked. The resin has an average pore diameter of 10-100 nm, an internal surface area of 10-100 m 2 /g and 5-15% cross-linking.
