This work investigates the potential of in situ NH3 removal for the sorption-enhancement of the NH3 synthesis. The experiments further show that a complete removal of NH3 is desired to fully exploit the potential of sorption-enhancement in the kinetic regime to avoid the kinetic inhibiting effects of already small quantities of NH3. In perspective, this observation underlines the importance of optimizing configuration of the catalyst and sorbent. Application of a physical mixture of catalyst and sorbent in upcoming investigations might be the most promising approach to increase the potential of sorption-enhancement. The present work, however, focused on the clear quantification of the sorption-enhancement, which is not possible in physically mixed beds due to superimposed and correlated kinetic effects. In addition, the development of industrially applicable reactor types for the combination of catalyst and sorbent together with operational strategies for a sorbent regeneration need to be developed
