Abstract

Abstract Solid sorbents have received extensive research as an alternative to aqueous amine scrubbing to remove CO2 from gas streams due to their theoretically lower energy requirements. Amine-functionalized sorbents are among the solid sorbents with the highest CO2 capacity. In this study, a recently developed amine-functionalized sorbent with a high capacity for CO2 is characterized using multiple techniques, including 13C NMR. These characterizations show that the sorbent is thermally stable up to 200°C and is stable when used up to ten sorption–desorption cycles.
