Hydrotreating processes that remove sulfur from feeds; these are usually not also effective for hydrodesulfurization. See Hydrotreating.

Process involving a reaction with hydrogen to remove sulfur compounds from hydrocarbon feedstock.

Hydrodesulfurization (HDS) 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.http://www.theicct.org/documents/Yamaguchi_Mexico_2003.pdf Hydrodesulfurization Technologies and Costs Nancy Yamaguchi, Trans Energy Associates, William and Flora Hewlett Foundation Sulfur Workshop, Mexico City, May 29-30, 2003 The purpose of removing the sulfur is to reduce the sulfur dioxide (SO2) emissions that result from using those fuels in automotive vehicles, aircraft, railroad locomotives, ships, gas or oil burning power plants, residential and industrial furnaces, and other forms of fuel combustion.
