Beschreibung
Zusammenfassung:	A method for processing a nitrogen-containing starting gas mixture by vacuum pressure swing adsorption, in which the starting gas mixture is temporarily guided under pressure in a main flow direction through an adsorption unit filled with an adsorbent material. The adsorbent material is provided, in a first region along the main flow direction, predominantly or exclusively in the form of first adsorption bodies; the adsorbent material is provided, in a second region along the main flow direction and downstream of the first region in the form of second adsorption bodies; that at least the second adsorption bodies are provided as composite bodies that have an inner core of a non-porous, non-adsorbent material and an outer layer formed from the adsorbent material; and that the second adsorption bodies have a lower proportion of the adsorbent material, in the body volume, than the first adsorption bodies.
