Abstract Catalytic oxygen removal applying a commercial CoMo‐based catalyst has attracted scientific attention owing to its catalytic stability towards poisoning components and cost‐effectiveness. The catalytic performance of the CoMo catalyst was investigated using statistical optimization techniques. The H 2 S concentrations in the sulfidation and reaction mixture are the key factors regulating the optimal values of deoxygenation reaction. The sulfidation process is a key step to generate the active species. The catalyst remains active in the presence of sulfur compounds in the reaction mixture, which is poisoning for other catalyst systems. An increase in the H 2 S content enhances the catalytic activity via in‐situ sulfidation within the meaning of regeneration during the reaction. Concentrations above 450 ppm H 2 S in the reaction mixture result in a nearly complete oxygen conversion and ensure the catalytic stability. At the same time, an increase in the H 2 S content favors a high sulfidation degree resulting in the formation of active sites.
