Hydrodesulfurization - Wikipedia
Hydrodesulfurization (HDS) is a catalytic stone 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. The purpose of removing the sulfur, and creating products such as ultra-low-sulfur diesel, is to reduce the sulfur dioxide (SO 2) 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.

James G. Speight, in Heavy Oil Recovery and Upgrading, 2019. 2.6.7 Biocatalytic Desulfurization. Biocatalytic desulfurization (BDS) is often considered as a potential alternative to the conventional deep hydrodesulfurization processes used in refineries. In this process, bacteria remove organosulfur from crude oil fractions without degrading the carbon skeleton of the organosulfur compounds.
