Abstract[English]
A method of treating a process waste stream contaminated with fluorinated hydrocarbons, the method comprising: adding a fluoride anion scavenger to the process waste stream; and contacting the process waste stream with a platinum group metal catalyst to defluorinate the fluorinated hydrocarbons liberating fluoride anions which are scavenged by the fluoride scavenger.[French]
L'invention concerne un procédé de traitement d'un flux de déchets de procédés contaminé par des hydrocarbures fluorés, le procédé comprenant les étapes consistant à : ajouter un piégeur d'anions fluorure au flux de déchets de procédés ; et mettre en contact le flux de déchets de procédés avec un catalyseur à base d'un métal du groupe du platine pour défluorer les hydrocarbures fluorés, libérant des anions fluorure qui sont piégés par le piégeur de fluorure.
