Abstract The following orientational study uses a factorial experimental design (DoE) strategy to determine the influence of different process parameters on the catalytic removal of oxygen traces (4500–9000 ppmv O 2 ) from coke oven gas by commercial Pt/ γ ‐Al 2 O 3 . Along this line, various experiments have been performed from 1 up to 11 bar and 150–250 °C with a gas hourly space velocity between 20 000 and 25 000 h −1 . The statistical analysis demonstrates that the applied temperature and pressure have a significant impact on the oxygen removal process. Experiments using gas mixtures with additional 350 ppmv H 2 S indicate a deactivation of the catalyst with a 66 % oxygen conversion at 250 °C and 6 bar. The close agreement between predicted and experimental data highlights the efficient approach for optimizing the oxygen removal from coke oven gas utilizing DoE strategies.
