Title (EN) ELECTROCHEMICAL CONVERSION OF HALOGENATED COMPOUNDS AND ASSOCIATED SYSTEMS
(FR) CONVERSION ÉLECTROCHIMIQUE DE COMPOSÉS HALOGÉNÉS ET SYSTÈMES ASSOCIÉS
Abstract:
(EN) Methods and systems for the electrochemical conversion of halogenated compounds are provided. In some embodiments, a method comprises converting a halogenated compound (e.g., fluorinated gas) to relatively non-hazardous products via one or more electrochemical reactions. The electrochemical reaction(s) may occur under relatively mild conditions (e.g., low temperature) and/or without the aid of a catalyst. In some embodiments, the electrochemical reaction may produce a relatively large amount of energy. In some such cases, systems, described herein, may be designed to facilitate the conversion of the halogenated compound (e.g., SF6, NF3) while harnessing (e.g., storing, converting) the energy associated with the electrochemical reaction. System and methods described herein may be used in a wide variety of applications, including waste management (e.g., environmental remediation, greenhouse gas mitigation), energy recovery (e.g., industrial energy recovery), and primary batteries (e.g., metal-gas batteries).
(FR) L'invention concerne des procédés et des systèmes pour la conversion électrochimique de composés halogénés. Dans certains modes de réalisation, un procédé consiste à convertir un composé halogéné (par exemple, un gaz fluoré) en produits relativement non dangereux par l'intermédiaire d'une ou plusieurs réactions électrochimiques. La réaction électrochimique (s) peut se produire dans des conditions relativement douces (par exemple, basse température) et/ou sans l'aide d'un catalyseur. Dans certains modes de réalisation, la réaction électrochimique peut produire une quantité d'énergie relativement grande. Dans certains de ces cas, les systèmes, décrits dans la description, peuvent être conçus pour faciliter la conversion du composé halogéné (par exemple SF6, NF3) tout en exploitant (par exemple, le stockage, la conversion) de l'énergie associée à la réaction électrochimique. Le système et les procédés décrits ici peuvent être utilisés dans une grande variété d'applications, y compris la gestion des déchets (par exemple, la réhabilitation de l'environnement, l'atténuation des gaz à effet de serre), une récupération d'énergie (par exemple, une récupération d'énergie industrielle), et des batteries primaires (par exemple, des batteries métal-gaz)
