For the reference case, 𝑊𝑇𝑌 is calculated according to Eq. ( ). For evaluation of the experimental data, the molar flow rate in the saturation phase, 𝑛̇ , , of bed configuration d) is used. This flow rate is formed by the total catalyst amount used in the experiment. Simulation provides direct accessibility to values of the outlet molar flow rate of NH3 without in situ removal.
