The authors develop a physics-based multiscale framework, systematically integrating a pore-scale Lattice-Boltzmann Method (LBM) model with a microstructure-aware macroscale breakthrough model, simulating coupled mass transfer and adsorption kinetics for a carbon-based COâ‚‚ sorbent. A screening of sorbent morphological parameters such as porosity and ratio of micropores/mesopores pertaining to hierarchical porous carbon nanofibers (CNFs) was conducted to delineate their influence on the adsorption performance.
