Title (EN) PROCESS AND APPARATUS FOR ELECTROCHEMICAL PRODUCTION OF SYNTHESIS GAS
(FR) PROCÉDÉ ET DISPOSITIF DE FABRICATION DE GAZ DE SYNTHÈSE PAR VOIE ÉLECTROCHIMIQUE
(DE) VERFAHREN UND VORRICHTUNG ZUR ELEKTROCHEMISCHEN HERSTELLUNG VON SYNTHESEGAS
Abstract:
(EN) The invention relates to a process and an apparatus for electrochemical production of synthesis gas, comprising the following steps: – reducing carbon dioxide to a first product gas comprising carbon monoxide in a carbon dioxide electrolysis cell, – splitting water to give a second product gas comprising hydrogen in a water electrolysis cell, wherein a first catholyte from the carbon dioxide electrolysis cell and/or a second catholyte from the water electrolysis cell is/are conducted into a gas scrubbing apparatus and the first product gas is freed of non-reduced carbon dioxide in the gas scrubbing apparatus by means of the first and/or second catholyte as absorbent.
(FR) L'invention concerne un procédé et un dispositif de fabrication de gaz de synthèse par voie électrochimique, comprenant les étapes suivantes : - réduction du dioxyde de carbone en un premier produit gazeux comprenant du monoxide de carbone dans une cellule d'électrolyse de dioxde de carbone, - décomposition d'eau pour obtenir un second produit gazeux comprenant de l'hydrogène dans une cellule d'électrolyse d'eau, un premier catholyte provenant de la cellule d'électrolyse de dioxyde de carbone et/ou un second catholyte provenant de la cellule d'électrolyse d'eau étant conduits dans un dispositif de lavage de gaz, le premier produit gazeux étant nettoyé à partir de dioxyde de carbone non réduit dans le dispositif de lavage de gaz au moyen du premier et/ou du second catholyte en tant que moyen d'absorption.
(DE) Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur elektrochemischen Herstellung von Synthesegas mit folgenden Schritten: - Reduzieren von Kohlenstoffdioxid zu einem ersten Produktgas umfassend Kohlenstoffmonoxid in einer Kohlenstoffdioxid- Elektrolysezelle, - Zerlegen von Wasser zu einem zweiten Produktgas umfassend Wasserstoff in einer Wasser-Elektrolysezelle, wobei ein erster Katholyt von der Kohlenstoffdioxid- Elektrolysezelle und/oder ein zweiter Katholyt von der Wasser-Elektrolysezelle in eine Gaswäschevorrichtung geführt werden und das erste Produktgas von nicht reduziertem Kohlen- stoffdioxid in der Gaswäschevorrichtung mittels des ersten und/oder zweiten Katholyts als Absorptionsmittel gereinigt wird.
