Study of Direct Air Capture (DAC) Using a KOH/K2CO3 Absorbing Solution for CO2 Capture

SSRN Electronic Journal, 2022
Direct Air Capture (DAC) consists of sequestrating CO2 from ambient air using absorption or adsorption mechanisms. Within the former, alkaline solutions, such as KOH, are generally used as the absorbing agent due to the high reached pH values favouring CO2 absorption. However, these solutions' alkalinity induces high corrosivity and harmful properties,
