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.sup.2 /g and 5-15% cross-linking.
Claims23
An adsorption material for olefins, comprising a thermostable resin containing strongly acid ion exchange groups to which Ag.sup.+ ions are linked, characterized in that the resin is a macroporous resin with an average pore diameter of 10-100 nm, an internal area of 10-100 m.sup.2 /g and 5-15% cross-linking.
A method of selectively removing olefins from a mixture of hydrocarbons comprising olefins and saturated hydrocarbons, in which the mixture to be separated is passed through a column containing an adsorption material for olefins comprising a thermostable resin with strongly acid ion exchange groups to which Ag.sup.+ ions are linked, characterized by removing a group of olefins of different carbon numbers selectively and reversibly from a gaseous complex mixture of hydrocarbons comprising olefins and saturated hydrocarbons of different carbon numbers by gas chromatography, by using a gas chromatography column containing a macroporous, thermostable resin having strongly acid ion exchange groups to which Ag.sup.+ ions are linked as an olefin adsorption material, which macroporous resin has an average pore diameter of 10-100 nm, an internal area of 10-100 m.sup.2 /g and 5-15% cross-linking.
