Abstract (en)
[origin: WO2009083275A1] The invention relates to a method and a filter for recovering low-boiling halogenated hydrocarbons (HHC), in particular for inhalation anesthetics such as desflurane, enflurane, isoflurane and sevoflurane. The method enables effective charging by adsorption and also effective regenerating via desorption by means of steam on two successive sorption beds which comprise hydrophobic molecular graded coal and hydrophobic zeolite.
