Development and Validation of a Multipurpose Setup for Synthesis Gas Chemistry

ABSTRACT This work presents the validation of a flexible multipurpose setup for studying synthesis gas reactions under industrially relevant conditions. It enables precise control of temperature (RT‐1050°C), pressure (1–100 bar(a)), and gas composition and is equipped with multiple online detection methods (IR, GC, QMS, and Raman). Reference tests on commercial catalysts demonstrate high reproducibility (±3.2%–5.2% deviation from specialized setups). Raman spectroscopy proved capability to detect all key species, whereas IR and GC offered superior sensitivity for NH 3 and MeOH, respectively. The MP setup successfully operated NH 3 decomposition (up to 30 bar(a)) and MeOH/NH 3 synthesis (up to 50 bar(a)/100 bar(a)). Its versatility makes it a powerful tool for detailed kinetic studies in synthesis gas chemistry.
