For the oxygen removal from coke oven gas (COG) the catalytic activity of commercial catalysts CoMo/γ‐Al₂O₃ and NiMo/γ‐Al₂O₃ was evaluated after a sulfidation pretreatment and compared to the Pt/γ‐Al₂O₃ reference catalyst. Elemental analysis and temperature‐programmed desorption showed that the oxidation reaction and the associated oxidation of active sulfidic centers is the main cause of deactivation despite the presence of other reductants, such as hydrogen. This approach could allow an appropriate sulfide catalyst to be designed for oxygen removal corresponding to the typical COG composition in the presence of H₂S.

合成焦炉煤气中的催化除氧：以Pt /γ-Al2O3为基准的硫化CoMo /γ-Al2O3和NiMo /γ-Al2O3催化剂的比较

对于除氧从焦炉气（COG）的工业催化剂的催化活性的CoMo /γ-Al系₂ ö ₃和的NiMo /γ-Al系₂ ö ₃被硫化预处理后评估和比较，以在Pt /γ-Al系₂ O ₃参考催化剂。元素分析和程序升温脱附表明，尽管存在其他还原剂（如氢），但氧化反应和活性硫中心的相关氧化是失活的主要原因。该方法可以允许设计适当的硫化物催化剂，以在存在H ₂ S的情况下去除与典型COG组成相对应的氧气。
