Abstract
Zeolite-supported Rh catalysts have been shown to be highly effective in catalyzing the oxidative carbonylation of methane to produce acetic acid. However, most of the research reported so far employed high-pressure batch reactors with long residence times. Continuous flow reactors have been seldomly used, with the majority of earlier works focused on ambient pressure studies. In this contribution, we constructed a high-pressure continuous flow reactor with steam cofeeding to bridge the knowledge gap that exists between these two distinct approaches. The production of CH3OH, CH3COOH, and other oxygenates, using a reactant mixture of CH4, CO, O2, and steam, was observed over Rh/ZSM-5 catalysts. The primary oxygenates, CH3OH and CH3COOH, reached productivities of 45 and 102 µmol/(gcat.•h), respectively. The influence of space velocity, Rh loading, Si/Al ratio of the zeolite support, and CO partial pressure were investigated.
