The dependency of the equilibrium H2 conversion on both temperature and pressure is shown in Figure for the same sorbent ratios as in Figure . In conventional NH3 synthesis, full or near full H2 conversion is not possible in the operating range investigated here, i.e. 1 -100 bar and 250 -500 °C. In fact, at temperatures relevant for acceptable reaction rates, the equilibrium conversion stays well below 50 %. This changes drastically when a sorbent is added to the system (Figure (b) -(d)): The equilibrium H2 conversion significantly increases over almost the entire temperature and pressure range already at 𝜆 = 2 and even further at higher sorbent ratios. Solely at high temperature and low pressures, or the very bottom right corner, the equilibrium conversion stays unaffected by the sorbent up to 𝜆 = 10. At these conditions, neither the synthesis nor the sorption reaction are thermodynamically favored and thus an unrealistically high amount of sorbent would be required to shift the equilibrium towards high conversion anyway. Generally, the higher the sorbent ratio, the wider is the pressure and temperature range in which H2 conversions close to unity are thermodynamically possible. It is particularly interesting when this area expands to temperatures above 400 °C, which are likely to be high enough to enable sufficient reaction rates.
