ELECTROCHEMICAL CONVERSION SYSTEM OF CARBON DIOXIDE

Conversion of carbon dioxide to oxalate: Eco-friendly system for high purity production

This technology is about an electrochemical conversion system of carbon dioxide in which carbon dioxide is electrochemically reduced to produce oxalate.

Reducing carbon dioxide emissions, the main cause of global warming, is an urgent task, but existing carbon dioxide conversion systems had limitations in terms of efficiency, purity, and environmental friendliness.

This technology is a system that electrochemically converts carbon dioxide into high-purity oxalate, using an amalgam electrode, an aprotic polar organic solvent (DMSO), and a specific By using auxiliary electrolyte (TBA·PF6), high purity oxalate of more than 90% can be produced in an environmentally friendly manner, solving the problems of volatility, explosion risk, and low purity of the existing system.

Key Features:

• A system that generates oxalate, a high value-added compound, by electrochemically reducing carbon dioxide
• Radicalizes carbon dioxide molecules in an aprotic polar organic solvent environment and then directly combines with other carbon dioxide radicals to form oxalate
• Uses a dental amalgam electrode that is harmless to the human body and has high selectivity for carbon dioxide reduction
• Can be operated at room temperature and pressure, and can be operated at a separate temperature There is no need for a control device or sealing system, so the device construction cost is low and the process is simple
