Abstract

Using MOR zeolite as a model, this study shows that controlled ball milling tunes particle size and intracrystalline diffusion pathways, balancing CO₂ diffusion and CH₄ exclusion. Moderate milling improves CO₂ mass transfer and delays breakthrough, but damages pore integrity, highlighting the trade-off between diffusion efficiency and molecular sieving.
