Hydrodesulfurization - Wikipedia
WEBHydrodesulfurization (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils.
Hydrodesulfurization | FSC 432: Petroleum Refining - John A.
WEBHydrodesulfurization. Desulfurization of fuels is commonly achieved by catalytic hydrodesulfurization (HDS), in which the organic sulfur species are converted to H 2 S and the corresponding hydrocarbon, as in the following reaction: R …
Hydrodesulfurization - an overview | ScienceDirect Topics
WEBThe hydrodesulfurization process is based on the addition of hydrogen to the petroleum fractions at elevated pressures and temperature in catalytic beds. Depending on the type of catalyst and operational conditions, there may be desulfurization, denitrification, saturation of fine oils, and cracking reactions.
An Overview of Hydrotreating | AIChE
WEBHydrotreating or hydrodesulfurization refers to a set of operations that remove sulfur and other impurities ( Figure 1 ). During hydrotreating, crude oil cuts are selectively reacted with hydrogen in the presence of a catalyst at relatively high …
Catalytic Hydrodesulfurization of Gaseous Fuels with …
WEBMar 1, 2021 · Hydrodesulfurization (HDS) is one the most widely practiced desulfurization processes in industry and efficiently removes different sulfur species via catalytic conversion to hydrogen sulfide. The generated hydrogen sulfide is then removed from the gas stream via adsorption processes.
Hydrodesulfurization - an overview | ScienceDirect Topics
WEBHydrodesulfurization (HDS) is the process that organosulfur compounds are removed over heterogenous catalysts during the refinement of petroleum. Failure to remove sulfur during this process results in the formation of noxious sulfur oxides, which are a major cause of air pollution, upon fuel combustion.

WEBJun 11, 2019 · The hydrodesulfurization process is one of the cornerstones of the chemical industry, removing harmful sulfur from oil to produce clean hydrocarbons. The reaction is catalyzed by the edges of MoS...
Recent Advances in Hydrotreating/Hydrodesulfurization Catalysts: Part …
WEBApr 2, 2021 · Hydrotreating/hydrodesulfurization is one of the important refining processes to improve the quality of petroleum fractions such as naphtha, aviation fuels, diesel, vacuum gas oils, and residue in terms of lower sulfur content and improved combustion performance.
Hydrodesulfurization - an overview | ScienceDirect Topics
WEBHydrodesulfurization is a critical part of oil refining, in which sulfur compounds including sulfides, mercaptanes, disulfides, and thiophenes from petroleum fractions are removed by high-pressure hydrogen treatment.
