What Catalysts are Used to Treat Refractory Sulfur Compounds?
Various types of catalysts are used to treat refractory sulfur compounds, including metal sulfides (such as molybdenum sulfide and tungsten sulfide) supported on materials like alumina. These catalysts facilitate the hydrodesulfurization process, where hydrogen is used to remove sulfur. However, the efficiency of these catalysts can be limited by the presence of refractory sulfur compounds.
