Abstract

L'objectif de la présente invention consiste à fournir un procédé et un appareil pour traiter un rejet gazeux contenant des composés contenant du fluor, selon lequel les PFC peuvent être décomposés de façon efficace et en plus le fluor provenant du produit de la décomposition peut être récupéré pour être réutilisé de façon efficace. Un mode de réalisation de la présente invention concerne un procédé de traitement d'un gaz contenant un composé contenant du fluor, procédé caractérisé en ce qu'on fait réagir le gaz avec de l'eau en présence d'un catalyseur comprenant de l'oxyde de tungstène supporté sur un support en oxyde composite d'alumine-zirconium dans une première étape et qu'on le fait ensuite réagir avec de l'hydroxyde de calcium dans un
