Hereby, the selective separation of the aimed compound can be done using different techniques. Next to investigations into the application of in situ membrane separation of NH3 , the sorptive removal is widely discussed. Especially for reactions forming water (H2O) as by-product, such as the methanation , the synthesis of methanol , and the synthesis of dimethyl ether , it was shown that the sorptive removal of H2O reduces unwanted kinetic or thermodynamic limitations on the reaction and increases the yields up to 100 %. In the case of NH3 synthesis, the sorption-enhancement aims towards the removal of NH3 as reaction product, which consequently shifts the thermodynamic equilibrium of the reaction towards a higher product yield according to Le Chatelier's principle. Recently, Movick et al. investigated the effect of in situ removal under kinetically limited reaction conditions, showing an enhancement effect of the sorptive removal on the reaction kinetics. Yet, experimental investigations of in situ separation remain scarce due to the challenging combination of a suitable sorbent and catalyst under reaction conditions enabling a sufficient rate of formation of NH3 and the simultaneous sorption.
