The removal of CO₂ from flue gases is one of the potential mitigation measures to address the climate change problem. To that end, adsorption is a promising technology that is currently being developed. The scope of the present work is to study the mass transfer profiles at multiscale levels for adsorption CO₂ and the effects of both macropores and micropores for different sorbents. A one-dimensional multi-scale model has been developed to produce breakthrough curves for adsorption CO₂ from gas streams using different capture material. The developed model matched literature experimental data reasonably well for three different sorbents at different operating conditions.
