Mehmood, Asad Iqbal, Muhammad Ibrahim Lee, Ju-Young Hwang, Jinyeon Jung, Kwang-Deog Ha, Heung Yong 2024-01-20T03:01:10Z 2024-01-20T03:01:10Z 2021-09-05 2016-11-20 0013-4686 https://pubs.kist.re.kr/handle/201004/123422 We propose a new configuration of a 3-compartment electrochemical cell for producing alkali that is subsequently utilized for mineralization of carbon dioxide. In this new membrane configuration, a second cation exchange membrane (CEM) replaces the anion exchange membrane (AEM) employed in a standard cell configuration. The electrochemical cell comprising of two cation exchange membranes (a CEM-CEM system) eliminates the issues associated with the AEM such as low ionic conductivity and inferior mechanical strength. All of tested CEM-CEM combinations exhibit superior electrochemical performance with considerable reduction of energy requirement for NaOH production in comparison to the standard AEM-CEM configuration. The optimized two-CEMs-based system presents a remarkable enhancement of output current density by 2.5-fold and a substantial input energy savings up to 740 kWh ton(-1) for mineralization of carbon dioxide to produce sodium carbonate.
