Abstract
AbstractWhen utilizing industrial exhaust gases for methanol synthesis, catalyst poisoning is an important issue. Long‐term in‐situ poisoning under industrially relevant conditions with sulfur‐containing molecules co‐fed into the feed gas flow and supplemented by extensive post‐mortem characterization of the catalyst bed is an efficient way to deepen the understanding of the poisoning mechanism and the different poisoning strengths of H2S, thiophene, and COS reported in literature. Unfortunately, such studies are rare due to the corrosive effects of sulfur compounds on typical lab‐scale flow setups. Therefore, this communication provides a detailed description of a setup built for poisoning studies using sulfur‐containing molecules under industrially relevant methanol synthesis conditions.
