Abstract

This study investigates the use of lysine-based deep eutectic solvent to modify surface properties of coconut shell activated carbon for CO2 adsorption. The prepared carbon samples were characterized for their surface morphology, elemental composition, changes in chemical bonds and surface area using ASAP nitrogen sorption, SEM-EDX and FTIR analysis techniques. Then, the breakthrough time and CO2 adsorption capacity of modified samples were performed in a fixed-bed reactor at low pressure environment. The modified sample at adsorption temperature of 25°C exhibited excellent surface morphology, rich in nitrogen species and highest breakthrough time. The breakthrough time and adsorption capacity of the modified carbon remained about the same as its initial adsorption (1^st cycle) after being reused more than 12^th cycles. This is confirmed that modified DES has high ability to achieve high adsorption performance.
