Abstract[English]
Zinc halogenated-triazolate oxalate metal-organic framework (MOF) sorbents constructed fully or partially with halogenated triazolate ligands, zinc, and a bidentate carboxylate are described herein along with their method of synthesis and its application for sorptive gas separation of carbon dioxide from a feed gas. The described zinc halogenated-triazolate oxalate MOF sorbents are suitable for applications where the feed gas has a reduced concentration of carbon dioxide and reduced levels of moisture. As compared to the prior art, the method of synthesis is environmentally friendly.[French]
L'invention concerne des sorbants à structure organométallique (MOF) à base d'oxalate de triazolate halogéné de zinc, construits entièrement ou partiellement avec des ligands de triazolate halogéné, du zinc et un carboxylate bidenté, ainsi que leur procédé de synthèse et leur application pour la séparation par gaz de sorption du dioxyde de carbone d'un gaz d'alimentation. Les sorbants d'oxalate de triazolate halogéné de zinc de l'invention sont appropriés pour des applications dans lesquelles le gaz d'alimentation présente une concentration réduite de dioxyde de carbone et des niveaux réduits d'humidité. Par rapport à l'état de la technique, le procédé de synthèse est respectueux de l'environnement.
