Title (EN) ION CONDUCTING MEMBRANES FOR SEPARATION OF MOLECULES
(FR) MEMBRANE CONDUCTRICE D'IONS POUR LA SEPARATION DE MOLECULES
Abstract: front page image
(EN)Bi-continuous membranes are provided in which one phase conducts a first type of ions and a second phase conducts a second type of ions. In some embodiments, a molten phase form one of the phase of the bi-continuous membrane and a solid phase forms one of th ephase of the bi-continuous membrane. The materials comprising the membrane are effective in separation and absorption technologies and are fabricated into a structured membrane in accordance with this invention. For example, to separate carbon dioxide, alkali metal carbonates, e.g., lithium carbonate, and solid oxides, e.g., zirconia, are suitable materials for the preparation of these types of membranes and can form CO2 selective and permeable layers.
(FR)L'invention porte sur des membranes à structure bicontinue dans lesquelles une phase conduit un premier type d'ions et une seconde phase conduit un second type d'ions. Selon certains modes de mise en oeuvre, une phase de fusion forme une partie de la phase de la membrane à structure bicontinue et une phase solide forme une autre partie de la phase de la membrane à structure bicontinue. Les matériaux constituant la membrane sont efficaces dans des technologies de séparation et d'absorption et sont fabriqués dans une membrane structurée, selon cette invention. Par exemple, pour séparer le dioxyde de carbone, des carbonates de métaux alcalins, tels que le carbonate de lithium, et des oxydes solides, tels que le zirconium, sont des matériaux appropriés à la préparation de ces types de membranes et peuvent former des couches sélectives et perméables de CO2.
