摘要： The invention is directed to a process for electrochemically converting a reactant gas, to an electrolyser, to a gas diffusion electrode, to a method for producing a gas diffusion electrode, to a gas diffusion layer, and to the use of said gas diffusion layer and/or gas diffusion electrode.
The process comprises reacting a reactant gas at a gas diffusion electrode to form a product gas and/or a liquid product,
wherein the gas diffusion electrode comprises a gas diffusion layer comprising a non-porous layer that is permeable to carbon monoxide and/or carbon dioxide gas, and a porous layer, and
the reactant gas comprises carbon monoxide and/or carbon dioxide.-

摘要： The invention relates to a heat integrated electrochemical process for converting a gas, such as carbon dioxide, using, for example, an electrochemical reactor. The process comprises
a) feeding a gas-containing absorbent into an electrochemical cell;
b) releasing a gas from the gas-containing absorbent by using thermal energy, wherein at least part of the thermal energy originates from Joule heat generated by the electrochemical cell, and c) converting the released gas to form a product.-

摘要： The invention discloses a method for in-situ extracting a reduced carbon dioxide product or product mixture in an electrochemical cell, and the use of a three-compartment electrochemical cell for in-situ extraction of organic carboxylic acids such as formic acid, acetic acid, oxalic acid, glycolic acid, tartaric acid, malonic acid, propionic acid, glyoxylic acid, and/or salts thereof for commercial use.
The method of the invention comprises introducing carbon dioxide-rich absorbent into a cathode compartment of an electrochemical cell, applying an electrical potential between an anode and a cathode in the electrochemical cell sufficient for the cathode to reduce carbon dioxide into a reduced carbon dioxide product of product mixture in the carbon dioxide-rich absorbent, thereby providing a carbon dioxide-poor absorbent, collecting reduced carbon dioxide product or product mixture via in-situ extraction into an acidic environment, and wherein the anode is separated from the cathode by more than one separator.-
