The influence of impurities in steel mill exhaust gases on ternary Cu/ZnO/Al₂O₃ 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 O₂ show reversible characteristics at low pressure. However, by increasing the partial pressure of O₂, poisoning becomes irreversible, indicating different poisoning mechanisms concerning the reversibility of deactivation.

钢铁厂废气中污染物对甲醇合成中Cu / ZnO / Al2O3催化剂的影响

对于常规甲醇合成，研究了钢厂废气中杂质对三元Cu / ZnO / Al ₂ O ₃催化剂的影响，这是Carbon2Chem®跨行业方法的核心反应之一。一系列碳氢化合物被确定为甲醇合成的惰性观众。几种催化剂毒物（如含N的化合物或O _2）在低压下表现出可逆的特性。然而，通过增加O ₂的分压，中毒变得不可逆，这表明了与失活可逆性有关的不同中毒机理。
