As stated above, the high sorbent ratios shift the NH3 synthesis equilibrium more than the lower ones, even though stoichiometrically, 𝜆 = 1 would be sufficient to absorb all NH3 produced at full conversion. The reason for this behavior is that the sorption equilibrium is dependent on the sorbent loading (eq. ( )). The corresponding sorbent loadings are thus shown in Figure (note that results for 𝜆 = 1 are displayed Figure ). By definition, the maximum sorbent loading is 𝜆 and reached at full conversion and total NH3 sorption. Hence, the maximum sorbent loading decreases with increasing 𝜆. At the same time, the maximum sorbent ratio is approached under a wider range of conditions at higher sorbent ratios, since the maximum sorbent loading can only be reached at full H2 conversion. These two parameters, i.e. H2 conversion and sorbent loading, are thus strongly interconnected. Values close to unity are desirable for both, but both is only possible at 𝜆 = 1. However, if high conversion is desired at kinetically relevant temperatures, higher sorbent ratios are necessary, which inevitably lead to a lower saturation of the sorbent. In other words: Low pressures and high temperaturesconditions not thermodynamically favorable for both NH3 synthesis and absorption -require a low sorbent loading (and thus a high sorbent ratio) as a sufficient driving force to overcome the unfavorable thermodynamic conditions.
