A side by side characterization of gas and liquid phase activation of a CoMo/Al2O3 hydrodesulfurization (HDS) catalyst is reported using thiophene HDS as a test reaction and CO adsorption monitored by infrared spectroscopy. The liquid phase sulfidation (high pressure, dimethyldisulfide) leads to the formation of CoMoS sites with higher intrinsic activity compared to the gas phase (H2S/H-2).
