Abstract

Cost-effective activated carbons for CO 2 adsorption were developed from molasses using H 2 SO 4 , H 3 PO 4 , HCl, NaOH, and KOH as activating agents. At temperature of 0 o C and pressure of 1 bar CO 2 adsorption equal to 5.18 mmol/g was achieved over activated carbon obtained by KOH activation. The excellent CO 2 adsorption of M-KOH can be attributed to its high microporosity. However activated carbon prepared using HCl showed quite high CO 2 adsorption, while having very low microporosity. The absence of acids species on the surface promote CO 2 adsorption over M-HCl.

Keywords: CO2 adsorption, activated carbon, molasses
