- •
Carbonation/calcination residence times critically affect the CO2 capture performance.
- •
Dolomite derived CaO shows higher CO2 capture capacity as compared to limestone.
- •
Best capture capacity behavior for dolomite is obtained for short calcination stages.
- •
Solid-state diffusion carbonation is critical at realistic CaL conditions.
- •
Prolonging the residence time in the carbonator enhances significantly the CO2 capture efficiency.
