Abstract

Die Erfindung betrifft ein Verfahren zum Entsorgen von in einer hohen Konzentration von beispielsweise 1.000 bis 1.000.000 ppm vorliegenden Ethylenoxid-Gas, wie es beispielsweise bei der Gassterilisation in Sterilisationskammern anfällt. Für die Entsorgung sieht das Verfahren vor, daß das Ethylenoxid-Gas mittels eines Adsorbens in dessen trockenen Zustand adsorbiert und/oder mittels eines Absorbens und/oder Katalysatorträgers in dessen durch Wasser nassen Zustand unter Anwesenheit eines Katalysators naß-katalytisch umgesetzt und/oder absorbiert und/oder mittels eines Oxidations- oder Reduktionsmittelträgers, welcher in Abhängigkeit vom eingesetzten Oxidations- oder Reduktionsmittel gleichzeitig als Katalysator und/oder als Füllkörper wirken kann, in dessen durch Wasser nassen Zustand unter Zugabe eines Oxidations- oder Reduktionsmittel oxidiert oder reduziert wird.
