Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur selektiven Entfernung und Rückgewinnung von Gas- und Dampfgemischen, die in verschiedenen technischen Bereichen, insbesondere im medizinischen Bereich wie in der Anästhesie, verwendet werden. Einzelne Komponenten der Gemische werden in sorbierenden Stoffen gebunden, während andere Komponenten diese passieren. Das sorbierte Gas wird durch Erwärmen der sorbierenden Stoffe desorbiert, in einem sich anschließenden Kondensator verflüssigt und einer Wiederverwendung zugeführt. Als sorbierende Stoffe werden bestimmte, dem Einsatzzweck durch Synthese oder Modifizierung angepaßte Zeolithe, insbesondere dealuminierte Zeolithe, verwendet.
