CARBON DIOXIDE RECOVERY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18318757 titled 'CARBON DIOXIDE RECOVERY SYSTEM
Simplified Explanation
The patent application describes a carbon dioxide recovery system that uses an electrochemical reaction to separate CO2 from gas containing CO2.
- The system includes an electrochemical cell with a working electrode and a counter electrode.
- The working electrode contains a CO2 adsorbent that absorbs CO2 through an oxygen reduction reaction.
- Electrons from the counter electrode are used to supply the working electrode with the necessary electrons for the oxygen reduction reaction when a specific voltage is applied.
- The oxygen reduction reaction produces active oxygen by reducing O2.
- The CO2 adsorbent releases CO2 by discharging electrons from the working electrode to the counter electrode when a different voltage is applied.
- The CO2 adsorbent also has a promoting function that enhances the oxygen reduction reaction.
Original Abstract Submitted
A carbon dioxide recovery system separates COfrom gas containing COvia an electrochemical reaction. The carbon dioxide recovery system includes an electrochemical cell including a working electrode and a counter electrode. The working electrode includes COadsorbent. The COadsorbent adsorbs COvia an oxygen reduction reaction by using electrons supplied from the counter electrode to the working electrode when a first voltage is applied between the working electrode and the counter electrode. The oxygen reduction reaction produces active oxygen via reduction of O. The COadsorbent desorbs COby discharging electrons from the working electrode to the counter electrode when a second voltage different from the first voltage is applied between the working electrode and the counter electrode. The COadsorbent has a promoting function for promoting the oxygen reduction reaction.
