摘要
A series of SK-activated carbons were prepared by carbonising soya beans in the presence of KOH as activation agent.Different activation temperatures were applied to study the influence of preparation conditions on the surface properties of the carbons and their CO_(2) adsorption capacity.It was found that the CO_(2) adsorption capacity is directly related to the nature of surface basic N-containing groups and that the highest CO_(2) adsorption capacity value was 4.24 mmol/g under 25℃ and 1 atm.
