For evaluation of the results the characteristic outlet molar flow rates, 𝑛̇ , and 𝑛̇ , , are used to estimate the sorptionenhancement factor. The weight-time yield for the sorption-enhanced case, 𝑊𝑇𝑌 , was calculated using Eq. ( ). Here, the half of the total catalyst mass was used, since this fraction represents the second half of the total catalyst bed, which is divided by the sorbent bed. It has to be considered that the first part of the catalyst bed does not contribute to the outlet molar flow rate of NH3 in the case of sorption-enhancement, since NH3 formed upstream is completely removed from the gas stream by sorption. Hence, 𝑛̇ , is synthesised by the downstream portion of the catalyst bed only, which equals half of the total catalyst mass 𝑚 in this work. This assumption is applied to both the simulation and experimental results for bed configuration d). We refer to Figure and Figure for illustration of 𝑛̇ , for the experimental and simulation case, respectively.
