Selective Electrochemical Regeneration of Aqueous Amine Solutions to Capture CO<sub>2</sub> and to Convert H<sub>2</sub>S into Hydrogen and Solid Sulfur

Selective Electrochemical Regeneration of Aqueous Amine Solutions to Capture CO<sub>2</sub> and to Convert H<sub>2</sub>S into Hydrogen and Solid Sulfur

Removing CO<sub>2</sub> from natural gas or biogas in the presence of H<sub>2</sub>S is technically challenging and expensive as it often requires separation of both acid gases from the gas, typically using an aqueous amine solution, followed by separation of CO<sub>2&l...
