The capture of CO_2 from gas streams has been achieved by the utilization of amine-enriched fly ash carbon sorbent system.The initial fly ash coarbon sorbents were generated by the chemical treatment of carbon-enriched fly ash concentrates with a 3-chloropropylamine-hydrochloride (CPAHCL)solution at 25 deg C.It was determined that these amine-enriched fly ash carbon sorbents performed at a 9% CO_2 capture capacity based on commercially available sorbents.The chemical sorption performance of these amine-enriched fly ash carbon sorbents will be described within this paper.
