Patent KR-20210155507-A (KR)
Inventor: CHANG HA LEE
IPC: H01M8/0668
Filed: 2020-06-16
Abstract: A carbon monoxide adsorbent according to the present invention exhibits excellent low concentration carbon monoxide adsorption performance based on a porous structure of a support, high active component surface distribution, and a large specific surface area of the active component. Through chemical adsorption of carbon monoxide, particularly strong adsorption characteristics are exhibited in a low pressure section, and low concentration carbon monoxide can be easily removed by high absorption strength. In addition, unlike the existing low concentration carbon monoxide removal method, it is expected that energy consumption and operating costs can be lowered because an additional process of injecting oxygen and removing carbon dioxide again is not required. Further, the carbon monoxide adsorbent of the present invention can be suitably applied to the production of high purity hydrogen used in fuel cells.
