The rates of desorption depend on the desorption driving force (the difference between the loading and the equilibrium loading) and the LDF constants. If the CO2 LDF constant is high, the desorption driving force can be lower whilst achieving the same rates of desorption, so the heating temperature can be lower, and hence less energy is required to heat the adsorbent bed. On top of this, a lower heating temperature additionally affects the H2O working capacity, which will also be lower, reducing the heat required for desorbing H2O. This is substantiated by the fact that the largest 2 nd order interaction for the impact of LDF constant on specific thermal energy is with the heating temperature. A sharper CO2
