The kinetics of adsorption of CO₂ on two low-cost biomass-based carbon adsorbents was explored.

The influence of the feed composition on the kinetics was evaluated by means of transient breakthrough tests.

Kinetic models were applied to study the rate parameters and the mechanism of CO₂ adsorption.

The main diffusion mechanisms involved in the adsorption of CO₂ are intra-particle and film diffusion.
