Document Type and Number:
WIPO Patent Application WO/2023/177298
Kind Code:
A3
Abstract:
The invention is a system (1000) for providing carbon monoxide and hydrogen. Especially, the system (1000) comprises an electrical cell comprising system (2000). Especially, the electrical cell comprising system (2000) comprises a carbon dioxide electrolysis unit (430). Further, the carbon dioxide electrolysis unit (430) comprises an anode (431), a cathode (432), and an ion-exchange membrane further comprising a cation-exchange membrane (413), or an anion-exchange membrane (414), or a bipolar membrane (415), wherein the carbon dioxide electrolysis unit (430) is configured to apply a potential difference selected from the range of 1.5-3V across the anode (431) and the cathode (432). Especially, the system (1000) is configured to convert in a first conversion process a carbon comprising stream (210, 220) to provide: (i) a carbon monoxide comprising stream (230), and (ii) an alkaline solution (240); wherein the carbon comprising stream (210, 220) comprises one or more of carbon dioxide gas, carbonate ions, and bicarbonate ions in an aqueous solution. Especially, the system (1000) is configured to electrolyze water in a second conversion process to provide a hydrogen comprising stream (250). Further, the system (1000) is configured to execute the first conversion process and the second conversion process in the electrical cell comprising system (2000). Yet further, the system (1000) is configured to pressurize one or more of (i) the carbon comprising stream (210, 220), and (ii) the carbon monoxide comprising stream (230) within at least part of the electrical cell comprising system (2000) at a pressure selected from the range of 10-70 bar.
