Title (EN) RECYCLING OF CARBON DIOXIDE INTO METHYL ALCOHOL AND RELATED OXYGENATES OR HYDROCARBONS
(FR) RECYCLAGE DE DIOXYDE DE CARBONE EN METHANOL ET COMPOSES OXYGENES OU HYDROCARBURES CORRESPONDANTS
Abstract:
(EN) A regenerative electrochemical cell system (10) based on a fuel cell (12) to oxidize methyl alcohol or other oxygenated hydrocarbons coupled with a regenerative cell (14) to reduce carbon dioxide to form oxygenated hydrocarbons is disclosed. Methods to reversibly interconvert oxygenated hydrocarbons and carbon dioxide, to recycle carbon dioxide produced as a by-product of industrial processes, and to store and release chemical and electrical energy are also disclosed. The carbon dioxide and water produced in the fuel cell may be supplied (16) to the regenerative cell, while the oxygenated hydrocarbon and oxygen produced in the regenerative cell may be supplied (18) to the fuel cell.
(FR) Cette invention se rapporte à un système (10) régénérable de cellules électrochimiques comportant une cellule électrochimique (12) conçue pour oxyder le méthanol ou d'autres hydrocarbures oxygénés, couplée à une cellule régénérable (14) conçue pour réduire le dioxyde de carbone de façon à former des hydrocarbures oxygénés. L'invention se rapporte également à des procédés permettant de convertir de manière réversible des hydrocarbures oxygénés en dioxyde de carbone, ou du dioxyde de carbone en hydrocarbures oxygénés, de façon à recycler le dioxyde de carbone qui est un sous-produit des processus industriels, et de manière à stocker et à libérer de l'énergie chimique et électrique. Le dioxyde de carbone et l'eau produits dans la cellule électrochimique peuvent servir à alimenter (16) la cellule régénérable, tandis que l'hydrocarbure oxygéné et l'oxygène produits dans la cellule régénérable peuvent servir à alimenter (18) la cellule électrochimique.
