Sulfiding, pre-sulfiding, or pre-sulfurizing is the activation process of hydrotreating catalysts that converts catalyst metal oxides into metal sulfides by reacting with H2S (Hydrogen Sulfide) in the presence of hydrogen gas. The sulfided metal form is the most active state of the hydrotreating catalyst and will facilitate the hydrodesulfurization reactions. The newly manufactured or regenerated … Continue reading Sulfiding of Hydrotreating Catalysts and its Troubleshooting
