Abstract

The invention describes a method for enriching at least one component from a gaseous mixture of substances, comprising the steps of (i) contacting a flow of a first gaseous mixture of substances which contains at least one component to be enriched, with a composite material at a first pressure p1 such that the at least one component to be enriched is adsorbed to the composite material and a charged composite material is obtained, said composite material comprising (a) a porous matrix of a fluorine-containing polymer having a percentage of tetrafluoroethylene monomer units of at least 95 mol % based on the total number of monomer units and (b) zeolite particles which are embedded in the matrix and around which matrix filaments extend; (ii) disrupting the flow of the gaseous mixture of substances and (iii) desorbing the at least one component to be enriched from the charged composite material by reducing the pressure to a pressure p2, with p1−p2≧200 mbar, such that a second gaseous mixture of substances is produced and removing the second gaseous mixture of substances from the composite material.
