Close‐to‐Practice Investigations of Heterogeneously Catalyzed Syngas Conversions in Slurry and Fixed‐Bed Reactor Systems

Abstract

In der Grundlagenforschung wird die Testung heterogener Katalysatoren normalerweise mit sehr kleinen Probenmengen durchgeführt. Eine Übertragung der ermittelten Ergebnisse hinsichtlich Produktivität und Standzeit auf den technischen Maßstab ist nur sehr eingeschränkt möglich. Es wurde ein neues praxisnahes Testsystem für heterogene Katalysatoren entwickelt. Es kann sowohl in Festbett‐Fahrweise als auch in Slurry‐Fahrweise in einem weiten Temperatur‐ und Druckbereich betrieben werden. Das System wurde für die Synthese höherer Alkohole und die einstufige Dimethylether‐Synthese erfolgreich eingesetzt.

Methanol Synthesis with Steel-Mill Gases: Simulation and Practical Testing of Selected Gas Utilization Scenarios

“…The practical tests were performed in a test setup for the conversion of syngas comprising a close-to-practice fixed-bed reactor system. The setup was developed as a modular system in which the reactor unit can be alternatively used as a fixed-bed reactor system or as a slurry reactor system [10]. For the described tests, only the fixed-bed reactor setup was applied.…”

Operating Behavior of a Demonstration Plant for Methanol Synthesis

“…On reactor level, a research task is to evaluate how the catalyst bed inside a reactor operates with varying synthesis gas compositions over time, how the temperature profile along the reactor develops with varying operating conditions and how it reacts to catalyst poisons that eventually slip through the gas cleaning unit. Such investigations with pure bottle gases to simulate the main compounds and real gases from the steel mill cleaned in a gas treatment unit at the Carbon2Chem technical center at the thyssenkrupp Steel Europe site in Duisburg, Germany, were performed with single pass test reactors in the first phase of the project cluster (2016-2020) and continue to date as part of the second phase [9][10][11][12][13].…”
