“…The temperature increase in pilot scale followed a clear trend towards higher conversion at almost stable product distribution which is quite a singularity reached by the reactor design, as reported before , . The low tendency towards deactivation at high conversion in highly diluted syngas raises hope towards a single‐pass reactor operation in the FT process with satisfying results.…”

“…Unlike the mechanistic model, which provides the potential possible mechanisms of the investigated reactions, the ANNs-RSM provides no insightful information regarding the reaction mechanism. 48,49 Once one individual microstructured unit in reactor is modeled by the robust and cost-effective modeling approach, the entire system will be convenient to be sized by means of simple addition, provided the sufficient and broad experimental operational conditions being well explored and investigated. On the other hand, its apparent accuracy in predicting product distribution and much easiness in converge during data regression are appreciably superior to the classical comprehensive kinetic model derived from LHHW approach when it comes to modeling the complex FT synthesis with limited computational resources.…”

“…Lastly, but not the least, the entire sizing and designing of reaction system in the micro-structured reactor is built upon simple addition rather than scaling up. 48,49 Once one individual microstructured unit in reactor is modeled by the robust and cost-effective modeling approach, the entire system will be convenient to be sized by means of simple addition, provided the sufficient and broad experimental operational conditions being well explored and investigated. Regardless of specific mechanism, as long as the multidimensional data were well collected, the established ANNs-RSM will provide a generic approach for accurately sizing the micro-reactors during FT synthesis.…”

“…Dadurch entstehen feine metallische Strukturen im Inneren des Reaktors. Somit kann auf kleinstem Raum eine große Oberfläche für Wärme‐ und Stofftransportvorgänge bereitgestellt werden , , so dass kein nennenswert begrenzender Einfluss mehr auf das Verhalten des chemischen Synthesereaktors zu beobachten ist . Die strukturierten Metallplatten haben je nach Stapelfolge die Funktion, den Katalysator in Form eines Festbetts mit dem Synthesegas unter optimierten Strömungsbedingungen in Kontakt zu bringen und die Reaktionswärme in ein Wärmeträgermedium abzuleiten.…”

“…Dabei wurden Methanselektivitäten und Kettenwachstumswahrscheinlichkeiten bei verschiedenen Reaktionsbedingungen und Strukturen mit unterschiedlicher Spaltweite verglichen und der Einfluss der Wärmeübertragung bewertet. Die Ergebnisse haben gezeigt, dass bereits die Erhöhung der Spaltweite von 0,8 mm auf 1,5 mm einen deutlich negativen Einfluss auf die Methanselektivität sowie die Produktausbeute haben . Aufbauend auf diesen Ergebnissen wurde die Entwicklung der Kernstruktur abgeschlossen und der Proof‐of‐Concept im Pilotmaßstab erbracht .…”
