What Role Do Sulfur Compounds Play in Hydrodesulfurization (HDS)?
In hydrodesulfurization (HDS), sulfur compounds present in petroleum feedstocks are converted into hydrogen sulfide (H₂S) and hydrocarbons. This process is essential for producing cleaner fuels with lower sulfur content. Catalysts used in HDS, such as cobalt-molybdenum and nickel-molybdenum, are specifically designed to facilitate the removal of sulfur while maintaining high catalytic activity.
