For kinetic analysis of the concept, a steady-state, pseudo-homogeneous reactor model was developed and both Ru and Fe kinetics were implemented. The model was applied for a simulation study in a broad range of operation conditions typical for NH3 synthesis with emphasis on the desired range for the sorption-enhanced process version (pressure range: 20 -100 bar, temperature range: 350 -450 °C, GHSV range 5000 -45000 h -1 ). Under these conditions, the Fe-based kinetics showed much higher activity than the Ru one. The near full H2 conversion predicted with the equilibrium model could be approached under a wide range of realistic operating conditions. Sorption enhancement generally allows for a higher NH3 productivity, while the H2 conversion is increased at the same time. Already at a sorbent ratio of two, the H2 conversion and the NH3 productivity can be boosted by up to 550 % at 350 °C, 100 bar, 15000 h -1 compared to the conventional process, indicating the vast potential of sorption-enhanced NH3 synthesis.
