The influence of impurities in steel mill exhaust gases on ternary Cu/ZnO/Al 2 O 3 catalysts was studied for conventional methanol synthesis, which is one of the central reactions within the cross‐industrial approach of Carbon2Chem®. A series of hydrocarbons was identified as inert spectators for methanol synthesis. Several catalyst poisons like N‐containing compounds or O 2 show reversible characteristics at low pressure. However, by increasing the partial pressure of O 2 , poisoning becomes irreversible, indicating different poisoning mechanisms concerning the reversibility of deactivation.
