Abstract: The invention relates to a method and apparatus for selectively removing and recovering gas and steam mixtures which can be used in different technical fields, in particular in the medical field such as anesthetics. Individual components of the mixtures are bound in adsorbing substances while other components pass these. The adsorbed gas is desorbed by way of heating up the adsorbing substances, is liquified in a following condensor and fed for reuse. For the desorbing substances zeolites are used which have been adapted by synthesis or modification for the application purpose, in particular dealuminated zeolites.
