While the thermodynamic analysis of SEAS confirms the feasibility of near full conversion over a wide range of operating conditions, the actual applicability of this concept further depends on the kinetic potential. In this study, both Fe-and Ru-based catalysts are considered. Figure shows axial profiles for both catalysts with and without sorbent. At the conditions applied here, the Fe catalyst is much more active than the Ru one, leading to much higher conversions in the conventional as well as the SE case. Similar behavior in the conventional case has been observed by Cholewa et al. , who derived the kinetics used in this work. as has been confirmed for the case of methanation in our previous work. This particularly holds for the Fe-based catalyst which is primarily inhibited by NH3. 19 In Figure , the H2 conversion reached in the reactor simulation is plotted against the equilibrium conversion. Some general trends are observable here:
