Naphtha hydrodesulfurization
WitrynaHydrodesulfurization (HDS) Hydrodesulfurization is the most commonly used method in the petroleum industry to reduce the sulfur content of crude oil. In most cases HDS is performed by co-feeding oil and H 2 to a fixed-bed reactor packed with an appro-priate HDS catalyst. The standard HDS catalysts are NiMo/ Al 2O 3 and CoMo/Al 2O Witryna2 kwi 2024 · Hydrodesulfurization (HDS) refers to the specific application of hydrotreating (HDT) for the removal of sulfur compounds from petroleum fractions such as naphtha, kerosene, diesel, VGO, and residue. Catalysts form the heart of the process because all of the hydroprocessing reactions occur over the surface of the catalyst.
