For a given space velocity and conversion, the productivity is fixed as indicated by the GHSV lines. At low GHSV, equilibrium is approached the closest and high conversions can often be reached. Due to the small throughput, however, the productivity is low. On the other hand, high GHSVs enable a higher productivity due to the increased throughput, which often comes at the cost of lower conversion. Increasing pressure generally leads to a shift towards both higher productivity and higher conversion. Yet, this effect is evidently more prominent in SEAS than in conventional NH3 synthesis. In both cases, the NH3 synthesis reaction is positively influenced by higher pressure, but in SEAS, the NH3 sorption is additionally favored. The temperature effect is ambiguous: At high GHSVs far away from equilibrium, a temperature increase leads to higher conversion as well as higher productivity. Towards the equilibrium, however, higher temperatures can be detrimental as the equilibrium is shifted to lower conversion. This can be observed mostly at 5000 h -1 , where different solution sets intersect.
