Abstract

Mesoporous carbonaceous materials (Starbons®) derived from low-value/waste bio-resources separate CO₂ from CO₂/N₂ mixtures. Compared to Norit activated charcoal (AC), Starbons® have much lower microporosities (8-32% versus 73%) yet adsorb up to 65% more CO₂. The presence of interconnected micropores and mesopores is responsible for the enhanced CO₂ adsorption. The Starbons® also showed three-four times higher selectivity for CO₂ adsorption rather than N₂ adsorption compared to AC.
